Samba – Create SAMBA node trust relationship to Windows 2003 PDC server

I am having problems creating a trust relationship
between an OpenVMS/IA64 node running V/IA64 8.3-1H1,
TCPIP 5.6 ECO 5, CIFS 1.1 ECO1 PS11 (SAMBA 3.0.28a)
and Windows 2003 server running as a PDC.

I do have two other OpenVMS/Alpha nodes running V/A 8.3,
TCPIP 5.6 ECO 4, CIS 1.1 ECO1 PS10 (SAMBA 3.0.28a)
with working trust relationships to the same Windows 2003 server.

Looking for assistance in resolving the trust "handshake".

Details from failing node.

Unless otherwise noted, corresponding files on working nodes
are similar or identical.

SMB.CONF extract:

[global]
server string = Samba %v running on %h (OpenVMS)
workgroup = WILMA
netbios name = %h
security = DOMAIN
encrypt passwords = Yes
name resolve order = lmhosts host wins bcast
Password server = *
log file = /samba$log/log.%m
printcap name = /sys$manager/ucx$printcap.dat
guest account = DYMAX
print command = print %f/queue=%p/delete/passall/name="""""%s"""""
lprm command = delete/entry=%j
map archive = No
printing = OpenVMS

Example from other node:

net rpc testjoin
Join to 'WILMA' is OK
