Paul,

If you are running Windows NT/2000/XP on your workstations and or server you
may find the problem to be caused by opportunistic locking. If you google
"opportunistic locking" you will find some interesting articles.

We resolved some major data corruption issues in VFP8 & XPProSP2 with
SBS2000 on the server by disabling opportunistic locking.

We used these files:-
Cut and paste the following into a file called woplocks.reg
and run it on the workstations

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkStation\Parameters]
"EnableOplockForceClose"=dword:00000001
"EnableOplocks"=dword:00000000
"UseOpportunisticLocking"=dword:00000000

Cut and paste the following into a file called soplocks.reg
and run it on the server or any machine that shares files

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]
"EnableOplockForceClose"=dword:00000001
"EnableOplocks"=dword:00000000
