Hi Nick--do you use the hash of the binary because there's a way round it if you just used the .exe name? So clever users can rename the file and be back online?

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. - - Nick
