I have a database with a frontend that was built in Access 2000 and at the
time we set it up with a SQL 2005 backend.

Recently we upgraded to Access 2007. SQL however was not upgraded. Is
there any known issues with the compatibility between these 2? We have been
experiencing system shutdowns and fatal errors. The frontend was not
converted to 2007.

We have also recently increased the amount of users and data sent to the
database.

Any thoughts?
