Answer 1

Hello.

The following worked for me:

Recompile .mof & .mlf files by running the following commands from an Elevated Command Prompt (Admin):

CD C:\Windows\System32\WBEM

dir /b *.mof *.mfl | findstr /v /i uninstall > moflist.txt & for /F %s in (moflist.txt) do mofcomp %s

Refresh "Server Manager" or re-open it

Answer 3

Hi,

Thanks for posting on our forum!

Firstly it's good for you to give us the error screenshot, however, apologize for not being able to read Turkish (?). I would appreciate it if you could translate the error message into English. When did this error message pop up on your Server Manager, what operation were you trying to do at that moment. I can only identify "...: Invalid namespace". Did the error message pop up when attempting to use WMI, as what @Anonymous suggested? We need more information to help you troubleshoot this issue.

Thanks for your support!

Hi,

Thanks for your response!

Based on your error message, your issue is probably caused by the serer manager can not connect the server Win RM service, please disable your proxy network then try again. More information can be seen from this blog:

I recently counter this error. File and Storage server tab was disappeared at the left pane of Server Manager and notification keep stating that refresh failed and reason was Invalid Namespace. This is what i've done to overcome it.

The step:

1 - i ran the command according to this link. please notice the directory for .mfl file as its all in en-US directory.

https://learn.microsoft.com/en-us/answers/questions/684166/failed-to-initialize-all-required-wmi-classes

2 - After completing above link, and refreshing Server Manager you will get new error notification of Invalid Nameclass. Then you run the command

1. cd C:\Windows\System32\wbem\AutoRecover
2. for /f %s in ('dir /b *.mof *.mfl') do mofcomp %s
3. goto Servermanager, do Refresh - Ok.

After this everything should be ok. at least for me.
