I am not sure how it got fixed but now it works. 

I deleted the registry key, deleted, and deleted their roaming profile from their home directory. And all works now.

Hello all,

          Let give the background.  We replaced our PDC with a new
machine.  Both old and new machines are running Debian 6.0 Squeeze and
Samba 3.5.6.  moved all data and user accounts to new server.  New
server has the exact same configuration files as the old server.  All
machines have been rejoined to the domain both WinXP and Win7.  The
WinXP machines work perfectly all domain users can login with their
roaming profiles and all is good.  However on the Win7 machines none
of the network users can log in to the machine.  Upon attempting you
get the this error "The Group Policy Client service failed the logon.
Access is denied."  After Googling around for a solution I have
attempted the following solutions:

1) Delete the roaming profile
       Machine recreates the roaming profile but denies login
2) Delete registry key from
       Machine recreates the key but denies login
3) Both 1&2 at the same time
       Machine recreates the roaming profile and the key but denies login

Any pointers would be greatly appreciated see smb.conf file below.
