Windows Server 2008, rejoining domain fails

Question

I have two windows 2008 servers, which have been unjoined from the domain for a long time.

I tried to rejoin them to previous domain and one of the servers could rejoin successfully, but the other one failed with the error: The following error occurred attempting to join the domain "my.domain"; Logon Failure: The target account name is incorrect.

I'm sure I used the right account, but still can't join to domain. Anyone know why?

Solution 1

Check if, by any chance, there isn't already a computer account with the same name in the destination domain.

Solution 2

Do the following on the machine on which you are unable to add to the domain:

arp -d *
nbtstat -R
ipconfig /flushdns

and then reboot the machine

Is the server still in AD? Try removing it from AD before you add it.

Really thanks all of your reminder! After I remove the host name from doamin, I could re-join this computer. Thanks a lot! Best Regards

Yes, I found this computer host name is already in destination domain.
