It was added to the default gateway in our LAN connection.

I inherited this setup and am still in the learning stages of dealing with
routers, DNS, and DHCP. I do appreciate any direction as to the best
solution. I would like to learn a bit more before I completly redesign the

Not to sound too ignorant but is this something I'll telnet into each of the
CISCO 2600 routers to setup?

My biggest question is still why this works fine on Windows2000 workstations
