[Samba] SAMBA PDC, WinXP SP1 - config attached!

[Nolan Garrett]

I am a SAMBA newbie, although I have spent many days perusing the newgroups 
and web for information before I posted my problem. I appreciate any time 
you put into helping me out. Here's my situation:

I can log on to the domain with my WinXP non-SP1 machine, works just fine, 
no problems at all. However, if I try to use either of my SP1 machines, 
here is what I get:

Windows cannot connect to the domain, either becuse the domain controller is 
down or otherwise unavailable, or because your computer account was not 
found. Please try again later. If this message continues to appear, contact 
your system administrator for assistance.

I have done the following:
1) Applied the requiresignorseal registry patch to both machines
2) Used gpedit.msc to enable the setting to ignore profile directories not 
owned by user

At this point, I am at a loss. I do have another problem that may or may not 
be related. If I try to view another machines shares other than the PDC 
shares, I get a message stating that I cannot access the network resource 
because "The trust relationship between this workstation and the primary 
domain failed".

Attached is my config. Any help you can give me would be much appreciated!
