I was having some trouble with Intelligent Message Filter so I thought I would just reinstall it. I went into add/remove and it went without a problem, the question is how do I REinstall it? I have Exchange 2003 SP2 installed but no tabs for IMF and no way to reinstall? Any ideas? Thanks Dan

Only IMF v1 was a stand-alone application, IMF v2 is an integrated part of Exchange 2003 SP2. So you can't re-install without re-applying SP2.

so can I safely reapply sp2? What would be my next course of action to get IMF functional again? We have other SPAM measures in place so I'm not ready for a ground up rebuild but if its just a matter of running sp2 again I can do that.

Yes you can safely re-apply SP2 without data loss. Only thing that will be overwritten is custom OWA logon pages. But just to be on the safe side you should always perform a backup of the server first.
