I'm not seeing duplicate zones i dont think.. at one point i think i had a
read only copy (or maybe secondary) on a third server 192.168.100.16.. but
not anymore..
In adsiedit.. I see the reverse lookup zone , domain.local and
RootDNSservers listed in there (under microsoft dns, under system, under
DC=domain, dc=local under the default naming context)
I did notice that this setting is in place on the dns servers (all are 2008
r2 at this point):
DomainNC (only for compatibility with Win2000):
Should i switch it to "to all dns servers running on dcs in this domain" ?
I dont actually see anything listed in the trusts anchors page..
Here are the ipconfigs (note, the best practices tool on r2, said that the
first dns should point to the Other DNS server, while the second is loopback,
doing this made the warning indication go away, but obviously didnt fix other
issues)
first is the first dc, called vsborg01:
