There are a lot of good resources that assist with administrative tasks within Windows Active Directory. One resource that I have found invaluable is found on the website of Richard L. Mueller. His Hilltop Lab site has been around for a while and he updates it quite frequently. You can find VBS scripts to run just about any AD task and if it is not exactly what you need, he has written the code in such a way that it is quite easy to modify.
