samba - Nov 2002 - smooth migration from nt4 doamin controller to samba pdc

Hello!

Today I started smbpasswd -S stualp.dom to get the SID of our domain.
The SID was successfully set to the samba server.

Then I started pwdump2 on our nt4 domain controller... the exported file
was imported with smbldap-migrate-accounts < sam.txt!

So I thought that I can shutdown the nt controller and activate the
samba pdc, but when I did this the workstation said machine accounts are
not (known) in domain or so ( translated from german). When I put them
into a testgroup, reboot and rejoin them everything is fine.

Do you have an idea how to make a smooth migration? I do not want to
rejoin all 150 Windows NT Clients... 

used software: suse 8.1, samba 2.2.7, openldap 2.1, modified
smbldap-tools, ...

	greetings Philipp Hellmich
