  • DNS issue?

    Hello!

    I just found out something strange...
    In cmd if I run nslookup twice, default server name changes:

    Code:
    C:\Users\User>nslookup
    Default Server:  dc2008.internaldomain.local
    Address:  10.10.0.70
    
    C:\Users\User>nslookup
    Default Server:  forestdnszones.internaldomain.local
    Address:  10.10.0.70
    Shouldn`t there always be DC2008.internaldomain.local?
    Why second run of nslookup gives other name?

    Now what is the secon one? I only have 1 DNS server configured in my TCPIP properties...

    Server is 2008 R2.

    Any ideas?

    Thanks!

    Hi,

    That forestDNSZone is default forest wide zone used for replicating you DNS settings based on replication type you select. There are two default zones for DNS ForestDNSZOne and DomainDNSZone

    The first one is coming from your reverse point records and second one is coming from ForestDNSZone

    You can see forestDNSZone using replmon tool.
    Thanks & Regards

        Hi,
        have you created an alias/cname for the your default zone as well.
        Thanks & Regards

          Nope, and the error went away?!
          Now no matter how many times I run nslookup, it always uses server
          dc2008...
          No more forestdnszones...

          Weird...

            OK, but it`s true, I changed DC IP yesterday...
            Maybe TTL had something to do with it...
