[Samba] DNS managment error

Interesting. Are Forest and Domain records being replicated in both 
directions from all DCs? It always worked from the WinDC to the S4DC but 
not in the other direction. Also, were you able to use the WIN DNS MMC 
to examine the DNS records on any of the Samba DCs? If so, you are 
probably close to having it working; something I never managed to do.

See ya...
