How to find Expired Users

I'm a Windows 2003 novice - paper MCSE on NT 4.0.  I'm in Network Engineering now - and usually hang out over there.  Hi ya'll.

Unfortunately, I have the responsibility of adding users to a domain which is used just for remote Internet Access through a company called iPass.  In a nut shell, I usually SSH into the server (maintained by the server group) and use a "net user /add *" command line to add them.

Because of some security B@#$4i+, I've had to create an auditing process whereby I now have to go in and set the accounts to expire as soon as I hear of someone leaving the company.

For example, if I get a notice that John Doe is leaving the company on 12/31/2006, I'll enter the command:

net user jdoe /expire:12/31/2006.  This will set his account to expire on that date.  All good.

However, in January, if I want to run a report to see all the users who stil have accounts, but are expired, how can I do this?  I don't see anything in the net user doc's and I don't see any options when looking at AT Users and Computers where there's a field for Account Expiration.

Thanks
