Blocking AIM/YIM/MSN/ICQ & Trillian
Posted on 2004-08-11
OK I am managing a win2k network with about 25 clients (XP & 2000) connected to the internet via a nexland 800 proturbo router. I would like to block as much IM traffic as I can. Currently I have most of the login servers for IM redirected on my DNS server to 127.0.0.1 and this seems to work well for blocking alot of the clients. Unfortunately Trillian just navigates around this somehow, does anyone have an idea of how to block this w/o installing additional software or changeing user rights?
