We have two sites connected by a SDSL link, we run a mix of W2K, NT and Linux machines as well as some Thin Clients with no problems. I've just built a new PC with XP Pro (Full, SP2 etc) but it won't get it to see the other side of the network (i.e. the other location) the SDSL connection is via two Zyxel 782R routers, these have been totally tranparent to the network thus far although they do have addresses assigned.

This is our first XP machine this side of the network and I just can't understand where or what the problem could be.

We use static IPs.
