Well wish me luck, I will be rolling out MS2007 next monday. I don't see any problems yet. I have been working with it for a few weeks. I only see one item that I am concern with.

In MS2003, if a previous user could not get into the database, all I had to do is re-join to the security.

In MS2007 I don't see anywhere that I can do that. Is there somewhere else that I should be looking?

Access 2007 dosen't support workgroup security. I believe you will have to leave the db in a prevous version to use wrkgrp security.
