I am moving an Access 2000 database to a new server (from NT4 to XP), and am having problems getting the security to move over. I'm obviously missing a step. I've copied my .mdw file to the new server, and joined that workgroup with Workgroup Administrator. I then copied some of the original databases that are secured by this .mdw file on my original server. When I open one of those databases, I get no login prompt, and there are no users or groups. Help!

What you might want to do is open up Access with the workgroup actually specified - this is also handy for when you have multiple workgroup files - and if you have different versions of Access (eg both 97 and XP), it often reverts back to the standard mdw.

So - you should open access using the /wrkgrp switch - for example:
