I have an 2000Access application which  run in several network
installations.
One of my customers claims that the application is very slow in his network.
On the server he has the table database (containing all his recorded data)

I'm encountering a crashing problem (database inconsistency) with a shared
Access 2002 database.  I've split a DB into a front-end (sales.mdb) and
back-end (sales_be.mdb) and there are approximately 5 users logged into the
DB at any given time.

I am running an Access 2002 database (split front-end and back-end) and would
like to LOCK the database on command (to update tables and avoid crashes for
inconsistency).  Is this possible?
Please let me know, thanks.
