System Centre 2012 SP1 Rollup 2 for VMM

 

Microsoft released Update Rollup 2 for System Centre 2012 SP1 a few weeks back but with this release there was one missing component – VMM. Last week Microsoft updated RU2 to include the fixes for VMM 2012 (under the KBs KB2826405 & KB2826392).

It is worth noting that you MUST uninstall VMM RU1 before you install this RU2 release, this is due to a problem with the original Update Roll up 1 and the way the files were packaged.

If you download RU2 from the Microsoft update catalogue and have already manually installed it, you must uninstall RU2 then uninstall RU1 and reinstall RU2 again. If you use WSUS for your updating you won’t receive RU2 until you have manually uninstalled RU1.

Microsoft has released an apology for all this installing and uninstalling you have to do:

‘We apologize for any inconvenience this causes your organization. We have performed cause analysis on the issue and have established processes to prevent future recurrences of this situation.’

The updated fix and list of updates are available here >> http://support.microsoft.com/kb/2802159

Error (0x0107, 0x0000) when trying to view a VM Console

I wanted to create a quick post about this just in case anyone else  ever has a  (0x0107, 0x0000) message when trying to view a VMs console session using VMM 2012.

Capture

This happens when you have a untrusted Hyper-V host in VMM 2012 such as a machine sitting in your DMZ (perimeter host). You will be able to see the Hyper-V host, the VMs and manage the VM properties but not connect to the console.  When you try to connect to the VM you will be asked to authenticate against the host and then you will see a warning about an un trusted certificate and once you click OK you will receive the (0x0107, 0x0000) message.

RDP

To resolve this issue you need to import the certificate from the Hyper-V host onto the machine where you are running the VMM console.

Logon to your Hyper-V Server and create a new MMC Console. Select the Certificates Snap-In to add use the ‘Services Account’

Step1

Locate the ‘Windows Remote Management (WS-Management)’ service account and complete the wizard with the rest of the defaults.

 

Step2

If like me your Hyper-V host is running Windows Serer Core mode instead of using certutil.exe you can use a snap-in on another machine (you will be asked to authenticate against) to remotely manage your certificates.

Once you have the console setup you need to find your server certificate which will be located under ‘WinRM\Trusted Root Certificate Authorities’. Right click on the certificate and follow the export wizard.

Step3

On your VMM console machine you need to import the certificate you have just exported into the ‘Trusted Root Certificate Authorities’ of the computer account.

STEP4

You should now be able to connect to the console of the VM. You will still need to enter your authentication details but you won’t be presented with the certificate warning.
