Question

After a recent system restore, I started seeing these errors repeatedly in Event Viewer. Any ideas how to fix/troubleshoot? I've tried sfc /scannow, dism /restorehealth, and various troubleshooters.

Hi AdamKessel-0270,

You may find that this error is being generated by a System file corruption. Under certain circumstances, you can also expect to deal with this issue whenever there’s an underlying corruption issue that forces your system to keep up with the creation of these DCOM events. To fix it, you can try doing DISM and SFC scans and work your way to a clean install or repair install procedure if the problem persists.

While SFC and DISM share some similarities, my recommendation is to run both in quick succession to improve your chances of fixing the corruption issue.

Please do the following from an elevated command prompt:

C:\windows\system32>sfc /scannow
C:\windows\system32>Dism /Online /Cleanup-Image /ScanHealth

After the DISM command is completed successfully, reboot your PC again and see if the problem is fixed at the next computer startup.

If the same ‘Unable to start a DCOM Server’ error is still occurring even after running both of these scans, you will likely need to perform a fresh installation of the operating system.

It started recently around in 2~3 month.

Did you guys abandon Windows?

You guys need to focus on your OS not the Azure.

Answer 3

As noted above, I have already tried the sfc and dism commands. I only started having this problem after a repair install.

Apparently 2147942402 relates to file not found -- how can I identify the missing file?

I'm now getting a slightly different error after trying various fixes:

I have been having a similar issue along with some more. There are 4 things that seem to come and go since updating some of our computers to 21H2.

-Right clicking any app pinned to the taskbar, this does not do anything (it should give options for opening)

I have tried sfc /scannow, all DISM commands, reinstalling searchapp, cortana, start menu experience host via powershell commands, deleting and recreating user profiles and reimaging computers (it just continues to come back) and I cannot find a fix.
