Are you using IP Sockets, or Named Pipes over Netbios over IP? The Netbios over IP scenario can be really messy over WAN links, as the routers must do all sorts of nasty broadcast-spoofing. Cisco's happen to be very good at this stuff...Try using IP sockets, if not are you using WINS/NBNS on the NT Servers? We have an SQL server that we access through a 56K link, and properly architected it can run very smoothly, like there is no WAN at all. Another thing to look for is ODBC. It tends to turn a simple 100 byte query into pages of crap, are you using ODBC? Dan.
