So you guys probably think us Microsoft folks have all the angles worked out. Well, if it makes you feel any better. I installed the Exchange Service Pack 2 without reading the release notes.
So, now I ended up in this funky state where I had IMF v1 installed on my home Small Business Server, with Exchange Service Pack 2. If you had read the Release Notes, you would know you're supposed to un-install the IMF v1 before installing Exchange Service Pack 2.
Luckily there was an easy fix.
- First Un-install the Exchange IMF v1 from A/R programs.
- Second, Re-apply Exchange Service Pack 2 to the machine
- Finally, to get the best experience, you should configure your server to get updates bi-weekly on the IMF v2 by simply following KB 907747 - How to update the Intelligent Message Filter version 2 in Exchange Server 2003 SP2
Now you're back to getting updates and have the latest IMF installed on your server.
