Certificate Error in SCVMM and its Host Server

Question

Hi,

We have a SCVMM 2012 r2 server hosted on a VM. This manages two Hyper-V 2012r2 Physical hosts on a Cluster. I am getting a warning message on VMM Server which says:

Warning (20583)
The self-signed certificate for computer is either already expired or is about to expire within a month.

Recommended Action:
Remove and add the from VMM to get a new certificate.

Any suggestion as how to renew this certificate. Its a production server hence need to avoid downtime.

Answer 1

Hello,

We can delete the expired certificate, and then run the following cmdlets in PowerShell.

1, Launch the VMM PowerShell on the Virtual Machine Manager server.

2, Type the following and press enter:

$credential = get-credential

3, Type the username and password that is a local admin on the VMM server.

4, Type the following and press enter:

Get-SCVMMManagedComputer -ComputerName "vmm2012sp1.contoso.com" | Register-SCVMMManagedComputer -Credential $credential

5, Ensure that the VMM job completes successfully under the Jobs tab in the VMM console.
