samba - Jan 2002 - ACLs on Solaris, plus migration

Has anybody migrated samba from one machine to the other? I have tried 
migrating from a PC running Linux to a PC running Solaris, and all worked 
fine at first, then when I turned off the original machine, the NT ACLs 
stopped showing up (the Solaris box happily reported the ACLs at the unix 
level)
I tried turning the original machine back on and, to my surprise, the 
domain attached to the ACLs was that of the original machine and the 
domain of the new machine.

I decided to leave well alone, until the ACLs stopped appearing totally. I 
now cannot get ACLs up and running on the Solaris machine, it happily 
allows me to go through the  procedure of selecting NT file permissions, 
only it comes back with "Unable to save permissions on <filename>.
Access
is denied".

My Samba is 2.2.2, any help would be greatly appeciated as I am now well 
and truly stuck.

my smb.conf follows:
$ cat smb.conf
# Samba config file created using SWAT
# from nomad174.uk.nomadsoft.com (192.168.2.174)
# Date: 2002/01/06 16:30:14

# Global parameters
