samba - Mar 2006 - renaming a domain and keeping everything else the same

We have samba 3.0.21c + openldap working ok.  Some weeks ago I got this 
answer (http://marc.theaimsgroup.com/?l=samba&m=113164752004902&w=2) to
my
question about whether it's better to have one or multiple windows 
domains, in favor of having only one domain.

Now, we're gonna put into production a NAS box (one Windows Storage 
Server) for our main domain and for our whole institution!  According to 
what I saw, it's seems that to work with only one unique domain is 
inevitable (500 users).

So we would like to rename our MAIN domain (type Windows NT domain) to the 
name of our institution.  Please, what is the proper (safer) way of doing 
this?  I think I understand that I must: to do the domain name change and 
to restore the samba domain SID generated because of the name change (is 
it ok?), but I would like to know about similar experiences, and any 
advise/warning.

Thank you!

Pablo
