Dear Friends, I need a solution of this problem. I have a Windows 2000 Server (working as Standalone Server) & 10 windows 98 based workstations & I'm working in a Workgroup model. I had installed ISA Server with Windows 2000 SP1 in the "Integrated mode".But the problem was that all the workstations were accessing the Internet, all the chat softwares were running on the workstations.But ISA Server itself was "not" browsing the Internet. Then I installed ISA Server in "Cache mode".The ISA Server and the workstations start browsing the Internet.But "MIRC" was not working on any side. Plz give any solution As Soon As possible. Regards.
