Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error. This can be done by opening your Outlook settings Tools and Accounts option. Now go to view/change the email account for the email account you are having problems with. After that check, the SMTP server is set to mail.yourdomain.com. Then click more settings and then click the outgoing server tab. See if the ‘My server requires authentication for the outgoing server’ is checked. If not, then check on it. Then simply save to confirm changes. Now try emailing again. Hopefully, this will resolve the issue.

Solution 3:

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.

As more and more people get into insider preview of upcoming Windows 11 we will see more and more different takes and opinions on it. Generally speaking, the first wave was quite positive when it was previewed but how time is passing more and more limitations and frustration comes to the surface. Some of the limitation that is inside it, which have been confirmed by Microsoft itself includes features missing that we had in Windows 10 like moving the application to the taskbar in order to pin it, moving the file in the taskbar to open it in default application and some big annoyances like Windows opening widgets always in Edge no matter what is your default browser. Not being able to move the taskbar from the bottom is also one of many illogical things. There is not really a point in these missing features since they were working fine in Windows 10 and many users liked them since they could customize Windows more to their liking, now with this new look at limitations it reminds me personally much of apple macOS and I will be honest, I am not a big fan of that kind of thinking. If I wanted that kind of OS I would have gotten myself a MAC, not custom build PC, but hey, Linux is always a free alternative, and how Microsoft itself is pushing limitations and in my opinion bad design choices along with awful system requirements that might just be a case for a lot of users. I am really not sure what is logic behind these moves and I am sure they have their reasons but this time it seems that their take on the new OS is not resonating well with the overall user population, well at least what I have heard so far. Things of course can still be changed and made for the better and I would rather see release postponed and issues addressed than getting more system hogging and limited new OS that at its current state looks like reskinned Windows 10 with limitations.

One of the preferred ways to upgrade Windows 10 is by creating a bootable USB drive. However, you might change your mind when you encounter an error during the Windows 10 Setup that says, “We can’t find a USB flash drive”. Worry not for this error can be fixed using some suggestions that will be provided in this post. The funning thing about this error in Windows setup is that the computer says it’s not there when it’s clearly there. To fix this problem, you need to check if the USB device is accessible on your computer or you can also try a different USB device. In addition, you could check if there are any issues with both the USB 3.0 and USB 2.0 ports as it could be the reason why you’re getting the error or fix the bad sectors in the USB drive as well as see if the USB drive is set as the primary drive.

Option 1 – Try to check if the USB is accessible on your PC

The first thing you can do to resolve the problem is to check if you can access your USB device from your computer. All you have to do is open File Explorer and check if the USB device is listed there or not.

Option 2 – Try to connect a different USB device

The next thing you can do to fix the error is to try connecting a different USB device, specifically the one that has more significant storage space. You also have to make sure that it’s working on a different PC.

Option 3 – Fix any issues with the USB 3.0 and 2.0 ports

Although the USB 3.0 ports are compatible with the USB 2.0 ports, it does not necessarily mean that there wouldn’t be any problem when you use them which is why it’s best to fix any issues in them or better yet, use a compatible drive.

Option 4 – Try to fix the bad sectors in the USB drive via CHKDSK

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 5 – Try checking if the USB is set as the primary drive

You might also want to check if the USB drive is set as the primary drive because if it is, then it won’t appear on the list. It could also be that the USB drive has a primary disk in it. To undo it, you need to use the DISKPART utility.

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• Next, execute the “diskpart” command to initiate the DISKPART utility.
• After that, type the “list disk” command and tap Enter to display the list of disks on the computer. You have to take note of the drive number or letter of the concerned USB drive.
• Once done, type the “select disk <X>” command where X is the drive letter or number and tap Enter.
• Then execute the “list partition” command to see the list of all the partitions in your computer. It should be listed as 0, 1, or 2. 0 is the primary partition.
• Now type the “select partition 0” command and tap Enter and then type “delete partition” to delete the selected partition.
• You can do the same to the other partitions as well and when you’re done, execute the format command to turn the USB drive into a standard one.

If you are trying to update your Windows 10 computer but are not able to do so since your computer is running low on storage then this obviously indicates that there is not enough disk space available on your drive where Windows 10 has been installed. As you know, when Windows 10 downloads the update packages, it extracts them in a separate folder which means that there should be enough space on that particular folder for the update to begin with. Windows do not really check systems for any adequate space requirements before it even initializes the update or upgrades and you only get to know about it right when the update process starts. On Windows 10 thin clients or the ones with embedded systems that have limited storage space, when Windows Update runs, the update initialization may fail because as pointed out, Windows does not check systems for adequate space requirements so you may have to do the work for them by making sure that your disk has enough space available. Here are some suggestions you can follow to resolve Windows 10 update issues on computers with low storage space.

Option 1 – Delete the files from the Download folder

Since you are going to delete everything manually, you need to create a backup for all your important files which you may have placed in the Download folder. After you create backup copies of important files, delete the files from this folder or you could simply tap the Shift + Del keys to remove the files permanently after you selected them all.

Option 2 – Change the Windows Update Folder location

You might have to change the Windows Update folder location where Windows download all the files need to update the operating system if you cannot really create some space on your primary driver. So all you have to do is set the drive with enough space available for the update to be completed.

Option 3 – Uninstall apps and programs you no longer use

In some cases, apps and programs take up a lot of space on your drive. So if there are programs or apps that you no longer use, you can uninstall them to save storage space. To do so, follow these steps:

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the apps and programs that you no longer use and right-click on each one of them and click on Uninstall.

Option 4 – Move files to another drive

This is another thing you can try. You can move files, especially the ones with large sizes, to another drive to make up space on your drive. After that, install the updates once again.

Option 5 – Reduce on-drive files from Cloud services

If you are using tons of cloud backup services such as OneDrive and Dropbox, you might want to consider reducing the number of files you have on those cloud backup services. You can do what you’ve done on option number three and have those files moved to another drive to free up storage space.

Option 6 – Empty the contents in Recycle Bin

As you know, the files that are deleted from your computer goes to the Recycle Bin first. So if you have not emptied Recycle Bin for a long time now, the files you delete are still actually taking up space on your drive. Thus, you need to empty the contents in the Recycle Bin to save storage space.

Option 7 – Clean up temporary files

You can use the Windows 10 Storage Sense feature which can clean all the temporary files from your computer. To use Storage Sense, follow the steps below.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
• Windows Upgrade Log Files
• System created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.

Code 0x800F0923 – What is it?

The Error Code 0x800F0923 is one that appears only when attempting to update from older versions of Microsoft Windows to Microsoft Windows 10. This error does not occur with every install and is believed to be the result of a driver incompatibility issue. It is unclear which specific drivers are having the compatibility issues, though it is widely believed that DuplexSecure's SPTD drivers are the ones at fault. When operating correctly, without errors, the update process should not take longer than 30 minutes. Common symptoms include:

• Error message window/pop-up during the install process, giving the Error Code 0x800F0923
• Inability to install and update from older versions of Microsoft Windows to version 10

Solution

Error Causes

There are various relevant factors associated with the error code 0x800F0923 incompatibility issue in Windows 10 installation/upgrade. These factors include but are not limited to:

• The Operating System (OS) upgrading does not support older hardware.
• Your computer’s specs did not meet the minimum requirements.
• Not enough hard disk space.
• The new software might lack software drivers for older hardware

Further Information and Manual Repair

Microsoft has recently released its Windows 10 operating system. While there are still a few kinks to be worked out, overall the reviews have been positive. As with any new Microsoft update, compatibility issues can arise. If you are unsure whether your current PC will be able to handle the new Windows 10, here is an easy way to check your system.

Method 1: Check if your computer is compatible

• Right-click on this icon, then select the “check your upgrade status” option.
• Be prepared for the menu to take a few minutes to open.
• Click on the menu on the upper left-hand corner of this new dialog box. (It looks like three blue horizontal lines)
• Select “check your PC”
• After the system checks for compatibility, it will let you know whether or not your PC has the appropriate drivers, etc. (Keep in mind that this is not a foolproof method for checking compatibility status).

Method 2: Download or upgrade your drivers/software

If you have already attempted to update to Windows 10, and have received the Error Code 0x800F0923, this is the simplest way to solve the issue yourself.

1. Open the “Get Windows 10” application. 2. Open the menu in the upper left corner, looks like three blue lines. 3. Select “Check your PC”. 4. The system will tell you which drivers are incompatible. 5. Go to the Microsoft Support website to install and/or update the drivers that proved to be an issue. 6. Once the driver issue is corrected, retry the Windows 10 update.

Method 3: Create space on your computer

If your computer does not have sufficient space to accept the upgrade, you might want to clear up some space on your computer. Here’s how to do it. If you have not attempted to install Microsoft Windows 10 yet, it is a good idea to check your system's compatibility prior to installing. While it is not absolutely necessary, it will save time and frustration. Microsoft Support suggests contacting them directly if you are unable to solve your driver compatibility issues, or if the above do-it-yourself method is unsuccessful. To resolve this compatibility issue and get your upgrade going use a powerful and user-friendly tool to clean up the problem. Click here to download Restoro. Users should also be aware that those who choose to upgrade to Windows 10 have 30 days in which they may decide that they would rather use their old system. However, reverting back to the older system may not be a smooth process, and some data could be lost.

Windows Updates are checked for their validity every time they are downloaded from Microsoft servers just like how browsers check websites for a valid certificate. And so if you got an error message saying, “ Some update files aren’t signed correctly, error code 0x800b0109 ” while trying to update your computer, it indicates that the Windows service was unable to verify the validity of the Windows Update. To fix this error, you can try out the options prepared in this post.

Option 1 – Reboot your computer and try again

Save your work and reboot your computer and then try checking for updates again. In some cases, all you need is a restart to fix errors like error code 0x800b0109.

Option 2 – Try to update Windows after an hour or so

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it an hour or so before trying to run Windows Update again.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error 0x8007001E. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “%temp%” in the field and press Enter to open the Temporary folder.
• After that, select all the folders and files within the Temp folder and delete all of them.

Option 5 – Clear the contents in the Software distribution and Catroot2 folders

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 6 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.

• There is not enough space for Windows 10 files in the primary drive
• There is not enough space in System Reserved Partition
• Windows 10 files are faulty or corrupt

More Information and Manual Repair

Method 1:

Clean boot Windows 8 and Windows 8.1: Whenever you get some unexpected behavior on your Windows 8, the first thing you should do is try to resolve the issue by taking a diagnostic approach. Plenty of factors can be the cause for issues like slowdowns, BSODs, computer freezes, sudden reboots, etc. The best way to detect the problem is to perform a clean boot. Using a clean boot, you can find out if the Operating System is damaged by some third-party app or bad driver. You can exclude the influence of these factors and prevent them from loading. You should do 2 things before you proceed with the clean boot. First, check if any third-party application is causing the problem. If you disable all third-party apps from startup, it will help eliminate software conflicts.

• Press the Windows + R on the keyboard. The Run dialog box will pop up.
• Type MSConfig in the dialog box and click "OK".
• The System Configuration utility will appear on the screen.
• On the services tab of the System Configuration dialog box, tap or click to select the Hide all Microsoft services check box, and then tap or click Disable all.
• On the startup tab of the System Configuration dialog box, tap or click Open Task Manager.
• On the startup tab in Task Manager, for each startup item, select the item and then click Disable.
• On the startup tab of the System Configuration dialog box, tap or click OK, and then restart the computer.

Now, close MSConfig.

Method 2:

The second step is a Safe boot. Follow the steps below for a safe boot:

• Press Win + R shortcut keys on your keyboard. The Run dialog will appear on the screen. Type MSConfig and press Enter.
• The 'System Configuration' application will appear on the screen.
• Switch to the 'Boot' tab, select your Windows 8.1 entry and tick the 'Safe mode' checkbox.
• Reboot your PC to enter the Safe mode of Windows 8.1.
• After you finish troubleshooting in Safe Mode, run MSConfig again from Safe Mode and uncheck the checkbox from step 2.

Method 3:

For this method, you will need to find the $Windows.~BT Folder in your primary drive which is C:. This folder might contain corrupt files which are preventing you from installing Windows 10. The folder is hidden and we need to unhide it. Follow the steps below:

1. Open File Explorer or alternatively double click on This PC or My Computer.
2. Now from the top option click on View, The Check the Box that says Hidden items.
3. Now you will be able to see hidden files and folders. Navigate to C:$Windows.~BT and Rename the folder to something like $Windows.~BT1.
4. Now, try downloading Windows 10 again. The installation process should go through this time without any errors like code C1900107.

Method 4: If the above methods fail, try this method:

1. Go to C:\Windows\Software Distribution\Download. Now delete all the files from this download folder. Remember, do not delete the folder itself, and just delete the files.
2. Now, delete the $Windows.~BT Folder. This might ask you for administrator permission. Simply click yes.
3. Now try to install or upgrade to Windows 10. This method should work fine and there should be no error code C1900107.

If you do not possess the technical expertise required to accomplish this yourself or do not feel comfortable doing so, download and install a powerful automated tool to get the job done.

This post will show you how to fix the Windows update error 0xca00a000 which you can encounter during the installation of Windows updates. Here’s the full error message of this Windows Update error:

“Updates failed There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: 2018-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4345421) – Error 0xca00a000”

This kind of Windows Update error pops up when Windows has missed installing one of the cumulative updates needed or when there is some problem with the driver that won’t let the installation of the updates push through. There are also instances when the system files are modified with incorrect permission that may result in the Windows update error 0xca00a000. Thus, you need to fix the trusted installer permission as well as resolve the issue with the driver. To do these things, you need to follow the options laid out below.

Option 1 – Run the Windows Module Installer

The Windows Module Installer is a built-in service in the Windows operating system that could help you resolve the Windows update error 0xca00a000. You need to make sure that this service is Started and that its Startup type is set to Automatic – you can do this via Services Manager or by executing the command given below in an elevated Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “command prompt” in the field and hit Enter to open Command Prompt.
• And in the elevated Command Prompt type in the following command and hit Enter:

SC config trustedinstaller start=auto

• After executing the command successfully, you should see the “[SC] ChangeServiceConfig SUCCESS” message on the Command Prompt window.

Option 2 – Try manually installing the updates

As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.

Option 3 – Delete the files from the Software Distribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

• Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.

Option 4 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

Option 5 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows update error 0xca00a000. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows update error 0xca00a000. This online troubleshooter is known to help in fixing Windows Update errors, it scans your computer for issues that might be causing the problem and then fixes them automatically.

A couple of Windows 10 users have reported an error on domain-connected systems when they tried accessing their computer systems remotely. This occurs when the network level authentication or NLA is enabled on the computer. If you are one of these users, you better keep reading as this post will guide you on how you can fix this error. To resolve this issue, there are several workarounds you can try. You can either disable this option directly via properties or you can also modify some registry entries or sub-keys and restart the system. When you encounter this problem, an error message pops up that states:

“The remote computer that you are trying to connect to requires network level authentication (NLA), but your windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box.”

Or you could also see this error message instead:

“The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support.”

Before you proceed in troubleshooting the problem using the options provided below, you need to create a backup for your data or system restore point as well as make a copy of any registry entries you are going to modify.

Option 1 – Disable Network Level Authentication via Properties

The NLA is a useful tool that provides your computer with extra security and helps network administrators in controlling who can log into the system with just a click of a single box. However, there are times when it can become a disadvantage and could prevent you from accessing your system remotely. Thus, you need to disable it using Properties.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” and tap Enter to open System Properties.
• Next, go to the remote tab and uncheck the checkbox for the “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)” option.
• Now click the Apply button to save the changes made and exit System Properties and then try logging into the remote computer again and see if the problem is fixed or not.

Option 2 – Disable NLA via Registry Editor

Note that you can only use this option if the first one didn’t work for you. Take note that this option will require you to restart your PC completely which could mean some downtime if your computer is running a production server. So make sure to save all your work.

• Tap the Win + R keys to open the Run dialog box and then type in “Regedit” in the field and tap Enter to open the Registry Editor.
• From there, click on File > Connect Network Registry and input the details of the remote computer and then try to connect.
• Navigate to the path below after you’re connected:

HKLM >SYSTEM > CurrentControlSet > Control >Terminal Server > WinStations > RDP-Tcp

• After that, change the values given below to “0”
