[Samba] Problems starting Server 2008 x64 after added to samba domain

[Robert Ludvik]

Hi
I have a problem with Windows Server Ent (and Std) 2008 x64 running on 
IBM Blade Center. I can add it to the Samba domain but when I restart 
it, it comes to "Applying computer settings..." and if I connect with 
rdesktop I can see a screen saying "Please wait for the group policy 
client" and after some minutes it restarts. I can boot it in Safe mode, 
remove from domain and it will start with no problem.
I have no issues with Server 2008 Ent 32 bit running on PC.
Any ideas where can I look for help? I installed all updates and SP2 ...
Regards
