When you 'join' a new DC to the domain, only minimal critical DNS 
records are created annd the GUID records are not amongst them. When 
Samba on the new DC is started, a script <samba_dnsupdate> is run (it 
then runs every 10 minutes after that). This script uses a file 
<dns_update_list> to check if various DNS records for the DC exist, if 
they do not exist, they are created, amongst these DNS records is:


So the GUID record possibly doesn't exist on your new DC because you 
haven't started it.
