[AccessD] Error # 3343 Unrecognized database format

Folks,

I have a client who has started getting an Error #3343 on their back end
DB.  The DB is Access 97. From what I can find on this error it usually
has to do with database writes being interupted or hard shutdowns.  They
claim that there have been no changes to thier network and that all
computers are working fine. I am going up to their site tomorrow to see
if I can figure out what is going on.  Any suggestions on what to look
for asside from the normal Access maintenance related things.  I am not
a network person so don't really know how to diagnose those types of
issues that might be causing this problem.

Thanks for any suggestions you can provide.

Doug
