How to block Windows Messenger net sends on a Cisco 2600
Does anyone know a quick and easy way to do this without using access lists? I am using IOS 12.x and would like to block the ports associated with the WIndows Messenger Service from coming into my company network. Thanks!

You need a real firewall, or to arrange with cisco to upgrade your IOS to a firewall feature set. You need to learn to love ACLs. You can block messenger with a simple ACL, but that will only stop that particular "vulnerability"
