[Samba] Domain Authentication Problem

One correction to my original email; I am running Solaris 9 rather than Solaris 8 (typo).
Following are my smb.conf settings:
workgroup = AMER
netbios name = USAHSSMC001
netbios aliases = USAHSSMC001
server string = EDS GSCO
security = DOMAIN
encrypt passwords = Yes
password server = usahd100 uspld100 usahd101 usahd102 usahd103 usahd104
username map = /etc/samba/username.map
log level = 4
preferred master = No
local master = No
domain master = No
dns proxy = No
create mask = 0664
name resolve order = lmhosts
My issue is: Everything was fine until the AD domain controllers were "upgraded" to Windows Server 2003 SP1. User authentication would no longer function until I pointed the password server entry to domain controllers that have not been upgraded to SP1.
I upgraded to Samba 3.0.21c, downloaded the pre-compiled version for Solaris 9 and installed with no problems. At this point, I cannot get Samba 3.0.21c to be recognized by either Windows Server 2003 or Windows Server 2003 SP1. I have tried rejoining the domain with no success.
Samba log entries:
cli_nt_create failed on pipe \NETLOGON to machine <name>. Error was NT_STATUS_ACCESS_DENIED
failed to get schannel session key from server <name> for domain <domainname>.
domain_client_validate: Domain password server not available
check_ntlm_password: Authentication for user [id] -> [id] FAILED with error NT_STATUS_TRUSTED_RELATIONSHIP_FAILURE
At this point, I can not get domain security to function for either Samba version when pointed to a Windows Server 2003 SP1 AD controller.
Any help with this situation would be appreciated.

It would help if you don't include all of the unnecessary stuff (especially comments)...
testparm -s > /tmp/samba-config.txt # would be better
your usage of
security = server
password server = ad
doesn't seem correct.
is ad a netbios name?
are you sure you want to use security = server and not security = ADS ?
at least you should make sure that 'password server = WHATEVER' has WHATEVER either an ip address or a resolvable domain controller.
see 'man smb.conf'
