Could not connect to the System Event

When performing a Windows Backup to the NAS device (backup to a network share) that is running Samba, fails with an error message The backup failed, The version does not support this version of the file format (0xC03A0005). The problem occurs because of a conflict with the VHD file that is created by Windows Backup and is mounted during the process. There are three types of VHD files:

1. Fixed,
2. Expandable
3. Differencing

If the VHD file is a sparse file that is not supported by the native VHD driver, the mounting will fail, and you will get this error. An example VHD file is one that keeps expanding depending on the backup size. The problem occurs only in the case of  File Level backup (file/folders in a volume) but not on the block level backup as the vhd file is never mounted. However, in the case of File Level Backup, the vhd is mounted, created by Windows Backup, which does not support the mounting of sparse files.

The solution is to use Strict Allocate: option in the smb.conf file

Login to SMB using SSH. Open the configuration file using the VI editor located at /etc/samba/smb.conf. If the option is not there, you can manually add strict allocate = yes which will make sure there are no sparse file that is created.

If you are trying to restore your computer using a System Image that has been created by the Windows Backup and Restore tool but encountered an error message instead that says, “Windows cannot find a system image on this computer”, you’ve come to the right place as this post will walk you through in fixing this error. Here’s the complete context of the error message:

“Windows cannot find a system image on this computer, Attach the backup hard disk or insert the final DVD from a backup set and click Retry. Alternatively, close this dialog for more options.”

In the error message, you are offered two choices – to either Retry or Cancel the operation. You can try to select Retry to try again but you will most likely get the same error if you do so. This kind of error can occur if the name of the WindowsImageBackup folder or any of its sub-folders has been modified. On the other hand, this error can also pop up if this folder or any of its sub-folders have gone missing or have become corrupted. To resolve the error, you can try to move the WindowsImageBackup folder or check its sub-folders. You can also try to isolate the System Image file or rename the System Image folder or remove all the unwanted sub-folders as well as use Command Prompt in Repair mode.

Option 1 – Try to move the WindowsImageBackup folder

The WindowsImageBackup folder must be stored in the root of the volume where it is stored, in line with the functioning of the System Restore utility. For example, if the WindowsImageBackup folder is stored in the “C:/Backups/System Restore Backups/New” location, then you have to move it to the C: drive as well.

Option 2 – Try to check the subfolders of the WindowsImageBackup folder

The classification of folders and files plays an important part to restore in restoring a computer from a System Restore point. Thus, if have modified the names of any files or folders inside the WindowsImageBackup folder, then you need to set the defaults. After that, run System Restore again and check if it fixes the error.

Option 3 – Try to isolate the System Image file

If the System Image file is stored in a USB storage device along with various System Restore images, then it’s no wonder why you’re getting this error. To set things right, you have to make sure that the System Restore image you wish to restore your computer from, is the only one that’s present at the root of the USB storage device.

Option 4 – Try renaming the System Image folder

If you have renamed the System Image folder prior to running System Restore, then it is most likely the reason why you’re getting the “Windows cannot find a system image on this computer” error. This error pops up because the System Restore utility in Windows 10 looks out for the WindowsImageBackup folder so if you have renamed it, you need to change its name back to what it originally was to fix the error.

Option 5 – Try to remove all the sub-folders of the WindowsImageBackup folder

If you have stored some foreign files inside the WindowsImageBackup folder, you need to get rid of them right away and return the folder to its default state as this folder must be left alone and should not be meddled with if you want to run System Restore smoothly.

Option 6 – Try to use Command Prompt in Repair Mode

• Open Command Prompt while your computer is in the Repair Mode.
• Next, type and enter this command where you need to replace “<Partition Letter>” with your drive’s letter: dir <Partition Letter>
• After you’ve found the WindowsImageBackup folder in any of the partitions, type and enter this command: dir <Parition Letter>WindowsImageBackup /s
• The command you entered will display all the contents of the folder exceeding 10 GB in total size. You can check and confirm the integrity of the folder and if you find that the integrity is violated, then it is the reason why you’re getting the error.

The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more. The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.

Option 1 – Sync Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Right-click on the Taskbar and click on the Adjust Date and Time option.
• Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
• Now make sure that the Time Zone that’s set on the same page is correct.

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BAD_SSL_CLIENT_AUTH_CERT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 3 – Try to check and fix any possible conflicts with third-party programs

Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.

Option 4 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.

• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Option 5 – Try to update Google Chrome

You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.

Option 6 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.

A couple of Windows 10 users recently reported getting an error that says, “The group or resource is not in the correct state to perform the requested operation” while opening UWP Applications as well as accessing the File Explorer. You can encounter this kind of error mostly on File Explorer, Microsoft Store application, and other UWP applications. This indicates that this error occurs during both the Windows Classic Application and the Universal Windows Platform Applications. There are several ways to fix this error. You can try to run a System File Checker scan, or run the DISM tool or the Program Compatibility troubleshooter or Windows Store Apps troubleshooter or try to reset or reinstall Windows 10 or the affected application that's not working. However, before you do any of these troubleshooting tips, you can try to perform System Restore first as it could undo the changes you’ve made in the system which might have caused the error.

• 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.

If System Restore wasn’t able to fix the error, then you can refer to each one of the following options.

Option 1 – Try to use the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the “The group or resource is not in the correct state to perform the requested operation”. To repair these corrupted system files, you can run the DISM commands:

• 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 and check if the DCOM error is now fixed.

Option 2 – Run the System File Checker Scan

Aside from the DISM tool, you can also run a System File Checker scan. It is another built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the error. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 3 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job. In addition, you can try to run the Windows Store apps troubleshooter as it can also help you resolve the problem.

Option 4 – Reset your computer

• Tap the Win key or click on the Start button located in the Taskbar.
• Then click on the Power button at the bottom right portion of the screen.
• Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.

Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen

• Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache. On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table. Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:

nslookup xyz.com Server: dns.company.com Address: 192.168.1.38 C:> ping xyz.com Ping request could not find host xyz.com. Please check the name and try again.

The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.

Option 1 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 2 – Force Windows to do a DNS lookup using FQDN

• Go to Settings > Network & Internet > Status > Change adapter options.
• From there, right-click on the network and select Properties.
• Next, in case you’re using IPv6, from the list of connections available in the list, select Internet Protocol Version 4.
• Then click on Properties and click Advanced.
• After that, switch to the DNS tab and select “Append these DNS suffixes (in order)” and click on the Add button and then add “.” as a suffix so that each time you query using PING and another tool, it will add a “.” at the end and will force the lookup.

Option 3 – Make sure that there is only one default gateway

If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.

Option 4 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 6 – Delete the WLAN Profiles

Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

Option 7 – Reinstall the Network Adapter Drivers

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and select “Uninstall device”.
• Restart your PC.

Error Code 0x80070004 on Windows 10 – What Is It?

Some users trying to upgrade from Windows 7 or Windows 8/8.1 reported experiencing installation rollback with error code 0x80070004. This error normally appears when the Computer Name is set to names that can’t be used for the computer. It’s also possible this error occurs if users or program files folder were redirected to a different partition.

Solution

Error Causes

The Error code 0x80070004 on Windows 10 is normally caused if any of the following were used as the Computer Name and the user tried to upgrade to Windows 10:

• System (or SYSTEM)
• SELF
• LOCAL
• Network

Failure to fix this error message might result in others, including error code  0xc0000001. 

Further Information and Manual Repair

If you don’t solve this error, you won’t be able to upgrade from Windows 7 or Windows 8/8.1 to Windows 10. Note that this error will continuously bring you back to the original OS unless fixed.

Please note that if you’re not confident in doing these steps, you might want to consider seeking the help of an expert or using an automated tool that will help fix this.

Here are a few methods to try.

Method 1: Check and Change the Computer Name

The most common cause of this error is if your computer uses any of the following reserved names:

• LOCAL
• System (or SYSTEM)
• Network
• SELF

These reserved names are not meant to be used as computer names. If this is what your computer uses and you try to upgrade to Windows 10, you will surely get this error. Check your computer name and if you see any of the reserved names, change it right away.

Changing Computer Name in Windows 8.1

If you’re trying to upgrade from Windows 8.1, you can change the name of the computer by following these steps:

• Step 1: Open the Start menu then simply type “rename computer”. After that, choose “Rename this computer”
• Step 2: A dialog box will open. Just click the “Change” button
• Step 3: A new dialog box will open. Type the new name. Click Apply then Ok.

Changing Computer Name in Windows 7

If you’re trying to upgrade from Windows, you can follow the steps below to change the name of your computer.

• Step 1: Go to the Start menu then on the Computer section, right-click the mouse and choose “Properties”.
• Step 2: A new dialog box will appear. Go to “Computer name, domain, and workgroup settings” then click “Change settings”. In case you’re asked for administrative access, make sure to grant it.
• Step 3: Find the “Computer Name” tab then click “Change”
• Step 4: Change the computer name and click Ok.

Method 2: Fix the “Users” directory issue

If the first method doesn't work, it probably means the computer name isn’t the cause of this error. Another reason why users experience Error code 0x80070004 when upgrading to Windows 10 is if the “Users” directory was relocated. So, when you try upgrading to Windows 10, the installer wasn’t able to find the user profiles on the “%systemdrive%”, where the current operating system is installed.

If you changed or moved any of the Users, Program Data, or Program Files folders, this will cause the error. Before you upgrade to Windows 10, you might be required to reset or reinstall your current operating system (Windows 7 or Windows 8.1).

If you haven’t made any changes or haven’t moved any of the mentioned folders, there’s a great chance that your users' profiles are corrupted. You can also reinstall your current operating system. However, you might want to check for the corrupter user profile first. To do this, follow the steps below:

• Step 1: Go to the Start menu and type System
• Step 2: Click System  then go to the Advanced tab
• Step 3: Go to Settings, which you’ll find under User Profiles

On the Users Profiles, make a copy of all the accounts somewhere. Sign out from the current user account then try logging in back using the accounts you’ve copied. For each account, you get an error, delete it. However, make sure that you don’t delete the UpdateUser and Administrator account ever.

After this is done, try upgrading your operating system to windows 10 again.

Coming in October for insiders and in November for all in the update, Microsoft has prepared a series of updates which they call an "additional set of experiences"

These updates are looked upon by Panos Panay, a vice executive president at Microsoft & chief product officer for Windows and devices as sort of makeup tests. They will consist of new additions with the biggest one being a tabbed version of File Explorer.

File Explorer received a UI makeover in the last update but the tabbed interface was missing which was expected by many users so it will come in following the next update.

The rest of the features that we will receive are an updated Photos application, Suggested Actions in the Windows Shell, Overflow menu for the taskbar, and improved Nearby Share.

The tabbed File Explorer interface is essentially File Explorer’s version of Sets, the tabbed window interface that Microsoft tested out several years ago. In testing, the tabbed interface proved handy for moving and copying files, and we’d expect the same once the feature formally goes live. The difference between Sets and the tabbed File Explorer interface is Sets allowed for multiple applications to be clustered together via tabs.

Photos app will include a “new photos-managing experience that brings a gorgeous gallery, simplifying browsing, finding, management and consumption of your collection of photos.” It will allow “easy backup to OneDrive” and a “delightful Memories experience.”

As for other features, nothing specifically was said except giving just some tips on what will they bring, it is obvious that File Explorer and the photos app were the main focus for MS in this upcoming update.
