This is confusing, you have upgraded from a PDC and you have called
your new DC 'PDC', so I hope you mean the old PDC was running openldap.

Try it like this: smbclient -L localhost

'domain' and 'search' are mutually exclusive in /etc/resolv.conf, or to
put it another way, you cannot have both, the last one wins, so I
suggest you remove the 'domain' line ;-)

Don't really know (yet), can you post:

/etc/krb5.conf
/etc/hosts
/etc/hostname
your bind conf files
