After your Windows is updated, check if the problem still appears.
3. Perform a Clean boot
Third-party applications can often start automatically with your PC and cause this and other errors to appear.
To fix this issue, many users are suggesting to perform a Clean boot. To do that, you need to disable all startup applications and services.
This is rather simple and you can do it by following these steps:
- Press Windows Key + R and enter msconfig. Press Enter or click OK to start it.
- Navigate to the Services tab and check Hide all Microsoft services. Click on Disable all.
- Navigate to the Startup tab and click on Open Task Manager.
- Once Task Manager opens you’ll see a list of all startup applications. Select the first item on the list and click on the Disable button. Now repeat the same steps for all entries on the list.
- After you disable all entries on the list close Task Manager. Now go back to the System Configuration window and click on Apply and OK to save changes.
After doing that, you need to restart your PC to apply changes. When your PC restarts, check if the problem still appears.
If not, it’s certain that one of your startup apps or services was causing the issue. To find the problematic application you need to repeat the same steps and enable apps and services one by one or in groups.
Keep in mind that you need to restart your PC after enabling each group of apps or services to apply changes. After you find the problematic app you need to disable it or remove it from your PC.
Alternatively, you can try to update the application to the latest version and check if that solves the problem.
4. Check your antivirus software
In some cases your antivirus software can prevent you from accessing certain directories. Even though antivirus is important, many antivirus tools tend to use certain policies that can interfere with your system and cause this and other system errors to occur. If you’re using a third-party antivirus software, we advise you to check its configuration and try disabling certain options. Keep in mind that each antivirus software is different, so you might have some problems finding and disabling the problematic feature.
If you’re not familiar with your antivirus and computer security, you might be able to temporarily fix this problem by disabling your antivirus. Even if you disable your antivirus your PC will remain protected thanks to the Windows Defender, so you don’t have to worry about your security.
You can also try to temporarily remove your antivirus. To do that, we strongly advise you to use dedicated removal tool to remove any leftover files. Many antivirus companies offer these types of tools for their software, so be sure to download one for your antivirus.
After you completely remove your antivirus, check if the problem still appears. If the issue is resolved, you might want to consider switching to a different antivirus software. Alternatively, you can try to install the latest version of your antivirus and check if that solves the error.
Solution 4 – Change your Web Publishing settings
If you’re experiencing this error while using ISA server, you might be able to fix it by changing few settings.

After enabling this option the error should be resolved completely.
Solution 5 – Switch to a different network

Solution 6 – Run chkdsk scan
If you’re still getting this error message it’s possible that your files are corrupted. File corruption can occur due to malware or power loss, but you might be able to fix your files using chkdsk scan. To do that, follow these steps:
- Press Windows Key + X to open Win + X menu and choose Command Prompt (Admin). If Command Prompt isn’t available, you can also run PowerShell as an administrator.
- Once Command Prompt starts, enter chkdsk /f X: and press Enter to run the command. Keep in mind that you need to replace X with the letter that represents the problematic drive.

After the scan, check if the error message still appears on your PC.
Solution 7 – Perform an SFC scan

Scanning process will now start. The scanning process can take a while, so don’t interrupt it. After the scanning is complete, check if the problem still persists.
In some cases you might not be able to run SFC scan or the scan might not be able to fix your problem. To fix the problem you might want to try performing a DISM scan instead. To do that, follow these steps:
- Start Command Prompt as administrator.
- Once the Command Prompt opens, enter the following commands:
- DISM /Online /Cleanup-Image /CheckHealth
- DISM /Online /Cleanup-Image /CheckHealth
- If any of these two commands report any corruption, you need to use DISM /Online /Cleanup-Image /RestoreHealth command. Keep in mind that this process can take a while, so be sure not to interrupt it.
After completing the scan, check if the problem still appears.
