I agree with Kevin.  The only thing I would add is to ensure all the networking settings are
correct.  It's been ages since I did Paradox on a network with multiple users...

LOCAL SHARE has to be TRUE.  Oplocks (Opportunistic locking) have to be disabled.  Disk caching
should be disabled.

Oh, and I wonder if the BDE's 4GB error could be causing this.  I never had to deal with this
so again, I don't remember the details.  I *think* it's a problem when there's an exact multiple
of 4GB of disk space free.  (Or was it 2GB?)  The newsgroups should have lots of discussion
on this issue.

Finally, perhaps one of the BDE file limits?  MAXFILEHANDLES might need to increase?  (I have
a doc from Mike Irwin recommending 150.  I'd probably set it to the max - 255.)

FWIW, here are the BDE settings I always use:

Configuration > System > INIT

RAM AMT. (MB)    256+      128

All which are True/False should be TRUE
MODE = 0
SEPARATOR = /
