Error 1601: Failed to retrieve WMI info. The RPC server is unavailable

Error 1601: Failed to retrieve WMI info. The RPC server is unavailable.

Checked the related problem handling….
But the state is still the same, the original environment has not changed
But the upgrade of windows 10 to 21H1 doesn’t seem to be possible

Is there a further way

Record it and let everyone know
Originally caused by normal results, Error 1601: Failed to retrieve WMI info. The RPC server is unavailable.
Remove WindowsUpdate kb5004945 and it will return to normal
This is the result of personal debugging

Getting same error.

I’m able to ping by name, able to access ADMIN$ share. I enabled printer and file sharing. still getting:

Error 1601: Failed to retrieve WMI info. The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

I tried portqry -n servername -e 135 and getting:

TCP port 135 (epmap service): FILTERED

Also tried turning off windows firewall completely.

Seems like another service is using port 135.Been going around in circles for a few days now. Anything else I could try?

@all – The error you’re getting is because BatchPatch is not getting a response to WMI queries against the target computer.

Any other tools I could try to troubleshoot this?

So I get RPC unavailable for this command:

get-wmiobject win32_service -computername servername

But this command works:

Invoke-Command -ComputerName servername -Authentication Negotiate -ScriptBlock {Get-WmiObject win32_SystemEnclosure} -Credential (get-credential)

I also tried specifying credentials in PatchBatch but still get an error.

I would suggest you follow all of the steps and links outlined at Troubleshooting Common Errors in BatchPatch
