Always cc to the list as well.

Disconnect the network cable on the new machine to make sure you are
not interfering with the rest of the network.
Start slapd then use slapadd to add your ldap to the database. Use
slapcat to verify that all was added and the ldif looks correct. Then
start samba and see if the smbclient can connect to itself.

Is the old machine the same name as the new? How about the ipddress?
Are you using wins, lmhosts or dns for your clinets to find the pdc?

BTW, I have to cut this a lot shorter than I want but I am very busy
at the day job and if I do not get my tasks done several new users
will not have a pc on Monday.
