I have a Windows Server 2003 Domain Controller, that I will call FOO. FOO's internal IP was recently changed from 10.20.0.1 to 10.50.0.1 .

This change has caused two extra DNS entries to exist for FOO besides the correct one: 192.168.0.1 and 192.168.163.1 . These subnets don't even exist on my network. When I try to delete them from DNS on every domain controller they just come back.

How do I get rid of these DNS entries so they do not come back?

Do you have any VMware products installed on FOO? It looks to me like you might have IPs for VMware virtual NICs being registered in the DNS.

Edit:

Sure thing. By default these NICs don't have TCP/IP bound to them. It sounds like you've got TCP/IP bound to two of them. Head into the "Network Settings" on the host OS. In the TCP/IP properties on each interface, go into the "Advanced" settings and uncheck the "Register this connection in DNS" checkbox on the DNS tab.

If you're running a DNS server on that machine too, alter the "Listen on:" setting on the "Interfaces" tab of the properties of that server in "DNS Management" to include only the IP address you want it to register / listen on for DNS.

  • Right on, there a work around to keep these interfaces from being populated into DNS?
