Re: [Samba] Internal DNS migrate to Bind9_DLZ




Hello Rowland,

I have already checked and the DN's are in AD, see attached.

SOA:
<domain>.corp.    3600    IN    SOA    psad102zadprh.<domain>.corp. . 9766
3600 600 86400 3600

See below NS, but the 1st NS (zatprdc001) doesn't exsit, and I cannot find
it anywhere.
NS:
<domain>.corp.    3600    IN    NS    zatprdc001.<domain>.corp.
<domain>.corp.    3600    IN    NS    psad102zadprh.<domain>.corp.
<domain>.corp.    3600    IN    NS    prdc001zacprh.<domain>.corp.
<domain>.corp.    3600    IN    NS    prdc001zafsrh.<domain>.corp.
<domain>.corp.    3600    IN    NS    prdc001zatcrh.<domain>.corp.
<domain>.corp.    3600    IN    NS    prdc002zacprh.<domain>.corp.
<domain>.corp.    3600    IN    NS    prdc003zacprh.<domain>.corp.
<domain>.corp.    3600    IN    NS    psad101zatcrh.<domain>.corp.

We did rebuild all our DC's to RHEL7.
We demoted on the DC being rebuild, then removed any and all records we
could find in AD/DNS. Rebuild the new server and rejoined.

Kind Regards
