Expired SCVMM certificate

1 comment January 3rd, 2018

In SCVMM 2012 R2 we suddenly couldn’t deploy VMs from a template, install “Virtual Guest Services Tools”, etc. All jobs failed with the following:

Error (2912)

An internal error has occurred trying to contact the server: NO_PARAM: NO_PARAM.

WinRM: URL: [], Verb: [INVOKE], Method: [GetError], Resource: [{62469246-350C-4ADE-A0BE-80D9E30C382D}]

Unknown error (0x80072f05)

Recommended Action

Check that WS-Management service is installed and running on server For more information use the command “winrm helpmsg hresult”. If is a host/library/update server or a PXE server role then ensure that VMM agent is installed and running. Refer to for more details.

We verified that we could connect to “” on TCP 5985 from the VMM server.


tnc -Port 5985

Checking the self-signed certificate on the VMM server it showed that it was expired. (01.01.2018)



Delete the expired certificate from the VMM server’s Personal Store and create a new one:


$credential = get-credential

Get-VMMManagedComputer -ComputerName “” | Register-SCVMMManagedComputer -Credential $credential

You will now get a new certificate which is valid for 5 years.
