Error 1753 - What is it?

Error 1753 is an RPC endpoint mapper error code. This code is typically displayed as "EPT_S_NOT_REGISTERED" or sometimes as the hexadecimal value 0x6D9.  Error 1735 indicates that there are no more endpoints available from the endpoint mapper. To understand this better, basically, RPC is an inter-process communication (IPC) method. This is used by clients and servers for communication purposes. RPC is used by programs to execute programs on a server computer. The perfect example of this is Microsoft Outlook. You communicate with Microsoft Exchange Server using RPC. This enables you to send and receive emails. When you use Microsoft Outlook to send emails, your computer sends a message to the server computer in an obscure coding. The server responds to your computer with another message that contains the results of the executed program. This is all being carried at the backend of the running program. Integral to this is the endpoint. The endpoint includes the name, port, or a group of ports on a computer that is monitored by the server for incoming client requests. This is a network-specific address to be precise. The endpoint mapper is the part of the RPC subsystem that is responsible for dynamically assigning endpoints to the server. When this function fails it leads to error 1753 message display. It shows that RPC service is not available.

Solution

Error Causes

The error code 1753 indicating RPC endpoint mapper service failure is triggered due to multiple reasons. These include:

• Windows registry damage and corruption

Each time you open an application inside your Windows 11 operating system, it is opened with standard privileges. Now, please note that your account privileges and application privileges are two different things, you might be the administrator of the system but when you open the app, it still opens with standard privilege. Most of the time running applications with typical settings is fine but from time to time we might have some applications that will require running with administrator privilege in order to work properly. In this case, it is very easy to do it, you just right-click and choose run as administrator. Although a very easy solution, it can be quite annoying if running the app is on a daily basis or even more times per day. If this is the case then right-clicking and choosing to run as administrator can be a daunting task, sometimes you can even forget to run it like this in heat of work and some unforeseen consequences might occur. Luckily there is an easy hack so you can open the chosen application each time as an administrator with a simple double click each time.

Setting application to run as administrator always

1. Locate application executable file
2. Right-click on in and choose properties
3. Click on the Compatibility tab
4. Check the box next to Run this Program as an Administrator
5. Click on Apply
6. Click on OK

From now on each time you open an application normally with a double click, it will be opened as administrator privileges.

PrintNightmare vulnerability has been a struggling issue for Microsoft in the past weeks, each time it seems to be addressed and fixed something new popped up and it still had issues. Microsoft finally addressed the issue but with a price. The default behavior of Point and Print is changed. From this fix onward, the Point and Print driver installation and update behavior will require administrator privileges, which should prevent the exploit to the Windows Print Spooler that could be used by malicious individuals to gain administrative privileges in Windows. The drawback of this fix from Microsoft is that non-elevated users may have difficulty adding or updating printers. Microsoft feels that the security risks caused by PrintNightmare are worth the tradeoff, though. If you really want to let non-elevated users add printers, you can follow the instructions in this Microsoft Support article to disable this mitigation with a registry key. However, doing so will expose you to this known vulnerability and isn’t recommend.

Technical Details and Manual Removal (Advanced Users)

If you wish to manually remove MyWebFace without the use of an automated tool, it might be actually possible to do so by removing the program from the Windows Add/Remove Programs menu, or in cases of browser plug-ins, going to the browsers AddOn/Extension manager and removing it. You will likely also want to reset your browser. Lastly, check your hard disk for all of the following and clean your computer registry manually to remove leftover application entries after uninstallation. However, editing the registry can be a difficult job that only advanced users and professionals should try to fix it. Moreover, certain malicious programs are capable to defend against its deletion. You’re advised to do this process in Safe Mode.

If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.

• First, go to the C:/Windows/System32/GroupPolicy/Machine location.
• And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
• Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
• After opening PowerShell, type this command: gpupdate /force
• The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.

• First, tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer.

There is a central location in Windows 10 that allows users to view all the notifications from its Action Center. Aside from viewing notifications, users can also manage them and take necessary actions in just one single place. Notifications in Windows 10 look similar to a message icon but can be at variance in function. However, recently, a number of users reported that even though they receive notifications about new actions but when opening them, they see nothing. In other words, the notification is false, and to fix this, read on as this post will provide you a couple of workarounds. The Windows 10 Notifications and Action Center notification messages might show a mismatch. For instance, Windows 10 may say that you have some notifications but when you open Action Center, you find it empty and there are actually no notifications there. Take the case of the following screenshot, the Windows 10 Notification says that there are 6 new notifications available for viewing but the Action Center says otherwise. Before you troubleshoot the problem, you might want to run System Restore especially if you’ve made some changes in your computer prior to this issue which might have messed with the Windows 10 Notifications and Action Center. To perform System Restore, refer to these steps:

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If the problem wasn’t fixed and you’re still getting false notifications, you might want to troubleshoot the problem further using the options given below.

Option 1 – via Windows PowerShell

• In the Start search, type “PowerShell” in the field and hit Enter to pull up the Windows PowerShell window.
• Next, copy and paste this command and hit Enter to execute it: Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppxManifest.xml” -verbose }
• After that, reboot your computer and check if the false notifications are now gone.

Option 2 – Try renaming the Usrclass.dat file

DAT errors like the ones that are associated with the Usrclass.dat file, most likely occur during computer startup, program startup, or while you try to use a specific function in your program. Even so, it can easily be fixed. How? Refer to the given steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type %localappdata%MicrosoftWindows and hit Enter to get to the location of the UsrClass.dat file.
• After that, look for a file named UsrClass.dat and once you’ve found it, right-click on it and select the Rename option.
• Now rename the file to UsrClass.old.dat and then restart your computer and see if the problem is now fixed or not.
