If you keep the same machine name, then it will not be an issue.

If you change the machine's name, then you should note the machine's
sid, and follow some of the advise on this list for manually setting a
machine/domain SID.

Samba 3.0 has command in 'net' to handle this, it's messier in Samba
2.2.

If your configuration is in LDAP, we make attempts to use the Domain SID
maintained in LDAP, to avoid some of these issues.
