Several years ago I used a script that could go through AD and give me a list of all the computer accounts that had not been logged into within the last x-number of days. Now I can't find anything like that. Does anyone know where I can find that? Thanks!

A script that shows the last logon time of a user can be found at http://certcities.com/editorial/columns/story.asp?EditorialsID=178. This might give you something to go on. There are lots of great resources on the Web for Active Directory scripting. A search on http://www.live.com/ brought up a number of other sites that could help you.
