The network is a NT 4.0 file server with service pack 3 (I've tested this with all and none service packs) using ethernet card and 1 active hub tied to 4 test pc's. Each is running TCP/IP and NetBUEI on either a Win98 or NT 4.0 with service pack 3 or 4. No bridge, router, no other server in this test environment. When the 2nd pc hits the same form performance drops by 300%. If I set the same test up on a Novell service using IPX as well as TCP/IP and NetBUEI, the darn thing runs fine. If it was something within the program, straight open the tables in the data environment with optimistic buffering, then I would think that both Novell and NT would show the same results.

Again, any help is really appreciated.
