I came across a problem where I saw that an extra DNS A record kept on being registered in DNS for a new SBS2011 server that I installed. This IP was not assigned to any of my network cards and this entry kept on re-appearing after I deleted it from DNS.
After some digging I found that it was the IP that RRAS was assigning to the server (This server is an AD and RRAS server).
So to resolve this:
- Open DNS manager.
- Right click on your DNS server and select properties.
- Select the Interfaces tab and remove the IP that was assigned to the server by RRAS.
4. Now delete the unwanted DNS entry (Host record) from DNS and this should be resolved.
