Hi there, this is my config, I have a CentOS 5.3  x86_64 full updated  
with Xen enabled with Samba 3.5.4 sernet RPMs. I have a virtual machine 
running Windows 2008 R2 Foundation running  full  virtualized on the 
same machine.
When i tried to join the Windows 2008 to the domain i get this message:
The following error ocurred attempting to join the domain "MYDOMAIN":
A device attached to the system is not functioning.

The Windows 2008 registry was modified to be able to join the domain as 
recommended on internet:
|HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters
DWORD DomainCompatibilityMode = 1
DWORD DNSNameResolutionRequired = 0

The LDAP was correctly populated, and i am able to manage users using 
smbldap-tools.
One final detail, when i tried to join the Windows 2008, in the joinning 
process the workstation trust account is successfully created. I see it 
with smbldap-userlist command or a Windows based Ldap administrator.
Apparently the Windows 2008 in its event manager does not give much 
information about the error.
If you need the samba joinning logs  with debug level 10 i have them.


Thanks for your help
