  • Wrong DNS entry keeps appearing for internal DC

    Hello,

    We have a bizarre issue whereby our WAN IP keeps being added to DNS pointing to our primary DC (DC01).

    As you can imagine this is causing all kinds of issues. Is there anyway I can see where this record is coming from? I have checked the server itself (DC01) and it has two internal addresses; no WAN IP assigned to it at all.

    Yet I deleted the WAN IP to DC01 record from our three Windows DNS servers and within 20/30 minutes it's back!



    Any ideas?

      Are you doing RRAS or NAT on this DC?
