I'm looking to block the access of AIM Express on our network. I'm aware of the port the AIM installed software uses, and have blocked it. When I run a network status in the command prompt (netstat /a) I'm seeing that one of the users is connecting to Aim Express on what appears to be port 6595. I just want to gain a second recommendation from everyone else that this is the correct port. Also, does anyone know if any other legitimate software uses this port? Thanks!
