JHT has written a specific chapter on migrating NT4 to samba in the Samba
Guide. I would gather that you may have already read it.

Try to get all of your machines upgraded to the same OS and version

The most robust seems to be to have your PDC machine also be a master LDP
server and then have LDAP replicate to slaves on the rest of your sites that
are also BDC's. Make you BDC's point to the slave ldap servers in your

Nope too hard. Not enough info unless you are guru status.

How are you doing it with your current setup? Does this meet your needs?

I'm kind of assuming that you have looked at the Samba Guide. A combination
of the Happy users chapter with some of the components of the distributed
2000 users network chapter, and a slight sojourn into the NT4 migration
chapter with some DHCP and dns configs pulled from chapter 3 & 4 should do
the trick. All the best, from a fellow migrator.
