[Samba] samba dc dns issue

[L.P.H. van Belle]

Hai, 

.. Small comment, im very very busy, due to corona. 


Setup your resolv.conf .. For the second dc and extras.

First, 

search your.dom.tld.
nameserver dc01

After the join, 
search your.dom.tld.
nameserver dc01
nameserver dc02

And after replication verifications. 

search your.dom.tld.
nameserver dc02
nameserver dc01


Try it.. 

Greetz, 

Louis
