One of our Access 2007 databases seems to have encountered some difficulties
with crashing. There are 18 users, and approximately 75000 unique records.
This morning the backend crashed and displayed the following error message:

unrecognized database format '\\r5\accumteam\prod2010\clmd_be.accdb'

r5 is the server name
The database then recreated a copy of itself, and all the tables were empty.
We were able to restore from backup but are very interested in fixing
whatever may be wrong
Thanks for any suggestions
