I struggled with the title for this request for help. I have server 2003 running and recently I had to rebuild 2 of the desktops attached to it. Before I did the rebuilds I removed them from the domain through the computers themselves and then I deleted them from the AD and added them back. After I rebuilt them I was able to rejoin the domian however I could never add a user to the system using the usual procedure through the user interface. I would get messages indicating the Domian could not be found etc. To compund things I could login as any user but they were always limited to 'user". I could login as administrator with full rights. I discovered that if I used a new NIC on each computer all this was avoided and I could add the user normally to the computer and they would have full rights.

So I figure the issue is tied to the mac address of the destop Nic and that someplace in the server AD I have to clear it. Can anybody shed a light on this for me?

Let me finish up by saying that at the same I added a new computer to the network and it joined and allowed user names perfectly. I have never seen this before.

Thank you

Chris
