Hello, I have a basic question: I have a group of clients that are not listed in the LAT, Client Address set, Protocol Rule, or Site and Content rule. Yet these clients are still gaining Internet access. Can someone please tell me how to eliminate these users from gaining Internet access? Keep in mind that the Protocol Rule and Site and Content Rule are set to only allow client address set to gain access. I am using ISA Server SP1 in intergrated mode. Thanks for your help.
