WINS Issue

Hi

I have two domains one located in England the other in Bahamas both running
Windows 2000 Server computer and Windows 2000 Professional clients. I have
a trust relationship setup between the two offices. DNS and WINS are
running on the networks. I am using WINS to faclitate browsing through My
Network Places, My Entire Network etc across the WAN. Is there a better way
to accomplish my goal. Also when accessing the file server across the WAN i
am getting an error, "Remote Procedure called failed" can anyone explain
why this is.

Thanks
