Hi,
Which Windows OS Version is not activated?
If you import this MP:
System Center Monitoring Pack for Windows Server Operating System
http://www.microsoft.com/en-us/download/details.aspx?id=9296
There is a docx file. Here is says:
-------------------------------
Disabled the following rules and monitors for Windows Server 2008 because the events needed are in Windows Server 2003 only.
• Duplicate computer name was detected
• Windows Activation State
----------------------------------------
