Stop usernames from being reused

I have been tasked with finding a solution to stop usernames from being reused for a certain period of time, in this case two years.  Is this something that can be done using GPO or will it have to be a manual process?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think this is more related to best practices. To be honest I don't think there is a way unless you leave the account disabled with in your active directory. This way if someone tried to create that same account it will warn them that it already exists. If you delete the user then there is no way to stop that from being created again.

Yep, best practice is to disable accounts and move them to a "defunct users" OU. Since two users with the same name are not possible, this will give anyone attempting to create on a warning.
