Microsoft Monitoring Agent & Windows Server 2012 R2? Some Attention Required

When you run SCOM 2012 R2 and are monitoring Windows Server 2012 R2 based systems some additional action is required.

Case
The SCOM 2012 R2 Agent (Microsoft Monitoring Agent) becomes greyed out on the Windows Server 2012 R2 based systems.

Cause
A lock in the OS code is hit when the PowerShell modules that ran a certain PS script are unloaded.

Solution
Apply the February 2014 update rollup as described in KB2919394. Read this posting on the SCOM Engineering Blog about this particular issue for more details.

!!!Warning!!!
Please be careful with applying this update rollup in your production environment since these updates might introduce new unwanted issues. So TEST them first before rolling them out in your production environment. I take no responsibility for any issues at all.
