What kind of server, NIC, HUB/Router, cabeling? I've run into problems with various configurations. After extensive investigation, I've gotten the hardware vendor's to admit some problem. Other times you can get them to tell you which NIC of hub they "recommend" for their system (i.e. had the fewest unresolvable problems with). My theory is that the speed of Foxpro will stress a system more than other apps and cause inherent problems to surface.
