We have recently setup an ISA Server on a Windows 2000 Server computer. The PDC is a Windows NT 4.0 computer. We had the ISA Server set for an IP address such as 192.168.1.201 and named the server ISA2000. We then changed the IP address of the ISA Server to 192.168.1.30. When I ping ISA2000 from another client, I get 192.168.1.201 instead of 192.168.1.35.
