Blocking Proxy Filters With ISA Server 2000

By Netmamed ·
I'm one of the administrators of a pretty good size Windows network (500+ users), and we are having a issue with Proxy filters. We run Windows 2000 Servers (DC1, DC2(ISA), and Exchange), with both Windows 2000 and XP workstations. My issue is that users are using proxy filters to access sites like myspace. Is there an entry i can apply to our ISA server to block these proxy filters (ex.,,, and are a few)? I've tried to just go in and block them one at a time, but there are millions of these sites that offer this service, and i just can't block them all. Is there a "wild card" entry i can use (ex. *, or *, because when i have tried these entries they don't seem to work. Any assistance would really be appreciated.

There is not always a technical solution to employee misbehavior. The managers of these employees should take control of the situation. Employee misbehavior is a management issue not a technical issue.
