.Net Framework Update causes this on W2k3 Servers

Here is rampant error I have seen after applying Windows Updates:

Event Type: Error
Event Source: .NET Runtime Optimization Service
Event Category: None
Event ID: 1103
Date: 9/16/2010
Time: 8:24:21 AM
User: N/A
Computer: BBB123
.NET Runtime Optimization Service (clr_optimization_v2.0.50727_32) - Tried to start a service that wasn't the latest version of CLR Optimization service. Will shutdown

Fixed it this way:
Downloaded: NDP20SP2-KB974417-x86.exe

1. Run NDP20SP2-KB974417-x86.exe -X
2. In the “choose directory” box, enter “C:\kb974417” (whatever you want to name it)
3. Then go to C:\kb974417, using explorer
4. Doubleclick the file NDP20SP2-KB974417.msp to install
5. Reboot your computer.

If you are using Windows Update server, you might have to reset:

At command prompt: wuauclt.exe /detectnow

Got to love updates!

I had the same error after a massive windows update session. Tried Microsofts "reinstall .net framework"-recommendation withouth luck, but the way you describe worked. Thx!
