I upgraded my Web Server from 2000 to 2003, and did a new install of ISA2006. Everyone is able to browse the internet OK and my exchange server works fine with it.
However, I cannot ping to the internal NIC. The server name cannot be resolved from the DC or my workstation, and the shares on the Web Server are no longer visible. I ran a tracert from my workstation and it resolved it, so DNS must still be able to find it.
I suspect ISA 2006 has seized control of it somehow, but am at a loss how it could block a ping to the internal NIC.
Anyone have any ideas what is different between ISA 2000 and 2006 that could cause this?
