We use a GPO with a Software Restriction Policy. We then restrict all IM programs via the hash of the binary. This can be hard to maintain because each new or old version you need to obtain the hash of the binary. I'm still in search for some master hash database. It works well for what its worth. Combined with other measures it works out pretty good.
Sorry, I should've mentioned that we're already doing this. This was the first thing we did in an attempt to stop IM. Unfortunately, these programs are updated so frequently that it's impossible to keep up with them. While this is good in conjunction with other methods, this alone isn't good enough (for us).
