Hi, I have ISA 2004 running in my organization but i've noticed at some systems that users are accessing MSN Messenger as well as Windows Messenger & sitting all day along. I have an access rule defined for users who are only allowed to browse the internet and cant even download any applications. I've also added the entire domain users in the Deny IM access rule in ISA 2004 but despite that they are still able to login.
Is there any proper way to completely block MSN Messenger & Windows Messenger through ISA 2004?
Second question: Is there anyway i can block IPs in ISA 2004?
Third Question: Is there anyway that i can provide users access to internet through ISA by just defining their systems IPs? currently i provide access to people who are members of a domain by their usernames.?
