I reinstalled XP on an Optiplex GX520 and now that I am trying to add the computer to the domain I am receiving the following message: "No mapping between account names and security ID's was done".
I was always able to add computers to the domain without any problems and I even downloaded and installed all of the required updates via Automatic Updates. Additionally, I never installed service pack 2, so I basically went from SP1 to SP3. Would that have anything to do with the message I am now receiving?
Thanks for your suggestion but unfortunately my problem is still not resolved. There are 2 more of the same type of computers on the network. Is there a file that I can copy over to the one that is giving the problems?
