I have a small network that uses Windows Server 2003. Clients use either W2K or XP. I am trying to restrict internet access for a few computers. I have filtered their IP's through the router but DNS automatically sends them out to the internet through the server. I have changed the dns on the two clients to point directly to the router (which restricts them). However I have software that requires access specifically to the server which is slowed dramatically because dns is no longer pointing there...any ideas on how to restrict clients another way?
