I formatted a machine and want to use the same name as before. When joining it says the account is already in use. I have deleted, re-created and reset the computer name with no success.

How long should i wait? Got 3 DC's

    If I recall correctly it can take about 4 hours to replicate... you may be able to add it once whichever DC your workstation is checking with has replicated - BUT you don't want to do this too early because what can happen is that it may get deleted again. This happens to me. If I delete the account in AD and then add the workstation, I will come in the next day and find that that workstation has been taken out of the domain.

    Don't forget to also remove any DNS Host Record, PTR Record or WINS Record left over from the old.

    It’s still a bit vague but after the force replication I was able to add the computer under its old computer name. Patience seems to be the key here. Everyone’s input is appreciated.
