Hi,
I believe I'm having the same problem as Marcin Giedz.
This is my case:
I've been running Samba 3.0.28a on Ubuntu for a few months.
One of my machines is running Windows Server 2008 SP2.
This machine joined my Samba domain just fine months ago,
however last week I reinstalled the PDC with Ubuntu and Samba.

Now I'm unable to rejoin my Windows Server 2008 machine to Samba.
When I try to join the domain I get this error:

"The following error occurred attempting to join the domain DEVNET:
The specified account already exists."

The Samba PDC seems to be working OK, since I'm able to
successfully join other machines running both Windows XP, Vista and Debian.
Changing the server name has no effect.

These lines are written to the Samba log during the joining process:
(DEVNET = My domain name, devadm = My samba admin user)

Any help would be much appreciated.
