I've got around 1500 users that I need to assign to 1 of 4 new groups in Active Directory. The AD is setup already so I was hoping I could just right click on the OU and assign it there and have it populate on down to the members underneath it. Either that can't be done, or I don't know how to do it. I tried the almighty Google but it came up with all sorts of stuff I have no idea how to use like VBScripting or WMI. Any quick and easy way to do this?
