AD Integrated DNS Question

-

i'm cleaning dns zones.

i'm noticing old entries in name servers tab. i'm going clean out via powershell.

my question is. need populate name servers tab if ad integrated?

since i'm removing old ones going add\update new ones.  being ad integrated i'd assume dc's getting copy authoritative.  why need populate tab?

i notice * next of entries.  makes me think auto-added.  if are, 'adds' them exactly?  since each dc contain copy i'd think wouldn't need go other dc\dns server in forest.

thanks in advance.

hi david,

run small test:

c:\>nslookup default server:  dnsservernamex address:  10.xxx  > set q=ns > google.com server:  yourdnsserver address:  ip  non-authoritative answer: google.com      nameserver = ns1.google.com google.com      nameserver = ns3.google.com google.com      nameserver = ns2.google.com google.com      nameserver = ns4.google.com  ns1.google.com  internet address = 216.239.32.10 ns3.google.com  internet address = 216.239.36.10 ns2.google.com  internet address = 216.239.34.10 ns4.google.com  internet address = 216.239.38.10 >
full list of name servers.

the dcs might not need other clients querying name server need have full list, if 1 talking goes down, has list which tells go next.

"* next of entries" must have seen descption says, ip result of dns query done @ time of addition of fqdn.

yes, gets automatically added whenever install new dc(in ad-integrated dns domain) or create new zone. if dcs missing, you can add them manually, auto-updates zone anyways. doesn't cleanup though.

allow ns record creation specific domain controllers

/allownsrecordsautocreation

required. specifies domain controllers entered value add names ns resource records zone specified in zonename. ns resource records registered zone not affected. therefore, must remove them manually if not want them.

if have issue existing ns or dc name not automatically created. autocreation tweaked someone.

on non-updating server run this:

dnscmd  <servername> /config  <dnszone>  /allownsrecordsautocreation

name servers disappear dns zone name servers tab
