Horrible day starts when windows 7 come into samba domain setup, i mean where Samba act as PDC. My setup is on RHEL 5 that use samba 3.0.33. Samab working as PDC is our setup. But now a days we are getting some windows 7 client. Adding windows 7 as a client in samba domain is really painfull. First of all what we need is to upgrade out samba. Samba wiki says that we require samba 3.3 at least http://wiki.samba.org/index.php/Windows7. From samba users i got fact that Windows 7 cannot join to Samba 3.2.11, can join to Samba 3.2.12 and 3.2.15, but a lot registry editing required. 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Para
meters]
“DomainCompatibilityMode”=dword:00000001
“DNSNameResolutionRequired”=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\]
“LmCompatibilityLevel”=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Netlogon\Parameters]
“Update”=”no”
“DisablePasswordChange”=dword:00000000
“MaximumPasswordAge”=dword:0000001e
“RequireSignOrSeal”=dword:00000001
“RequireStrongKey”=dword:00000001
“SealSecureChannel”=dword:00000001
“SignSecureChannel”=dword:00000001

But i think one must go for samba 3.3.x if windows 7 is going to be one of client of samba PDC.
If your Samba’s version is 3.3.2 – 3.3.4, then the additional settings
below are needed:
        HKLM\System\CCS\Services\Netlogon\Parameters
             DWORD  RequireSignOrSeal = 0
             DWORD  RequireStrongKey = 0

If your Samba’s version is 3.3.5, no need of above settings. But you must
do following settings. Remember you must not set above registry settings

      HKLM\System\CCS\Services\LanmanWorkstation\Parameters
           DWORD  DomainCompatibilityMode = 1
           DWORD  DNSNameResolutionRequired = 0
