You mention that for every service you _block_, two more show up. Shouldn't
you be sitting back and making your users make a case for business need vs.
security risk, and then _opening_ ports for their traffic, rather than
running around blocking ports you don't want them to use?
Here's the main list of well-known (tm) port-numbers:

I'm now the most unpopular person in the building blocking AIM, Realplayer,
Broadcast.com and other things along this route. The problem is is that for
every service I block two more show up. Does anyone know of a listing of
these services? A list of the port numbers they use would be great too;
installing and then sniffing everything is killing me.
