Event Viewer broken after sp3 update

[Nobody Important]

Trying to troubleshoot another error related to updating to sp3, I cruised
over to the Event Viewer to see what error codes I was getting.
Surprisingly, I found it non-functional. I can get a list of the four
standard event logs (Application, Security, System, Internet Explorer). But
clicking on any of them yields only an error message: "Unable to complete the
operation on "System". The interface is unknown."

Any insight or advice you can provide would be appreciated.

First - let's make sure the service is working...

Start --> Run --> type in:
services.msc
--> OK

Now scroll down to Event Viewer.
Double Click on it and make the Startup type Automatic from the drop down
box.
Click Apply.
Also click on the Start button to start the service.
Click OK.

Try opening eventvwr again...
