Hi
You should take a look at the routing table on thw w2k server, and make sure that the route:
Code:
10.21.7.0 255.255.255.0 10.21.7.55
points to the right interface (nic) !
when adding routes to w2k you can specify which interface the route should use, if you dont it will try to decide for itself. Maybe it got confused about the "same" address space with different subnetmasks.
btw.
You have got better control if you use "routing and remote access" console instead of just enabling routing in the registry.
good luck
