Windows Server 2003 SP2 Setup Fails - WMI Error

When installing service pack 2, the setup crashed and errored out.

This is what I got in my svcpack.log file located in C:\windows

After a bit of research I came accross this website by someone named Katy that showed my exact error, and showed that it was related to WMI problems:

This is a brilliant artical I suggest you have a read. My problem was a little bit different to Katy's. My WMI service didnt even exist!



When I went to the WMI control properties in computer management I got the following:



To get this back I ran the following in command prompt:

wmimgmt /regserver

This got the service back:



Setup then completed successfully.
