[Samba] Machine trusts after migration

[Phil Dawson]

I've migrated from windows pdc to samba and came across a strange problem. 
 When doing the migration everything went ok.  I vampired the accounts and 
created the group mappings etc.  The machine and user accounts came across 
ok.  The xp box I've been testing with was authenticating and could access 
the shares but was not seeing the samba box as the pdc.  Everything seemed 
to be set up ok.  What I had to do was enter system properties/computer 
name then select network id and re-create a machine account on the samba 
server.  After that the xp box would log onto the domain.  The funny thing 
is nothing seems to have changed on the samba server.  User and machine 
accounts are still there and haven't changed.  Secrets is the same.  Group 
mappings are the same.  Obviously, something would have changed on the xp 
workstation but I was under the impression the xp box should have used the 
new pdc as this pdc was the only one available to it for this domain.

Currently using samba 3.0.10-1.4E.

Can anyone shed some light on why this would happen?


TIA,


Phil
