Hi

I have a users site which is getting an intermittent 'Unrecognised database
format' error when connecting to an MSAccess 2000 database using ADO within
a Borland Delphi application.

The site consists on 10 client machines running a mixture of Win2000 and XP
machines all with the latest service packs (including XP SP2) and Jet Engine
SP8 installed. The clients are serviced by a Windows 2000 server with SP4.

Being an established site running the software successfully for the last 18
months this error has only been occurring during the last month or so. It
seems to occur randomly where they can have days without a problem and then
on another day they have to repair the database 5 or 6 times. Up to now we
have assumed that there must be a rogue machine causing the data to become
corrupted but after extensive testing, swapping of LAN Cards and isolation
of machines over the last month we have not been able to identify the cause
of the problem. Also as far I can tell from questioning the users IT Manager
no changes have been made to their systems which might have triggered this
problem.

Has anyone else had this problem, if so how did you resolve it, or can
anyone suggest the likely causes of this error.

Many thanks

Stuart
