>I have a server running W2K/SP4 and a workstation running WXP/SP2. I have a 1Gb NIC connecting the two on a back-to-back connection. Everything working ok.

>I run an app on the workstation which locks a record in a DBF file stored on the server. Then the workstation runs a job, which may be take between a few minutes to as much as several hours, and when it is done it updates the record in the DBF file and moves onto the next record which it locks and repeats this process.

>The connection to the server still appears good and I can access any files I want including loading VFP and opening the DBF manually. The program however cannot and I need to exit and restart it.

Do you mean you have the two computers direct-connected without a switch in the middle? If so:

- are both computers on UPSs or otherwise protected from power spikes/static etc.?
- are both computers well grounded with no chance of a ground loop between them, which might show up as a voltage potential on the interconnecting LAN cable?
- could you repeat your tests with a switch in the middle?
- is there any difference if you manually set your workstation speed to 100Mbit instead of gigabit, to force the slower connection for test purposes?
