RAS and DC IP Address confilcts in DNS

[ntaylor0909]

I have RAS Installed on my 2003 DC and am using it for VPN. I was
having trouble with DNS in my LAN and found that the DC's name was
resolving to one of the 10 IP addresses that RAS was reserving. I found
that this was the IP Address listed as the IP address of the internal
interface under the server/IP Routing/General section of RAS. I checked
DNS and there are two entries for my DC. one is the correct static and
one was the aformentioned IP address. Does anybody know what causes
this, and what is the solution. Thanks.

As we always say that it is not recommended to enable RRAS on a DC. Otherwise, you may have a name resolution issue in the LAN. Having said that, you may fix this issue by configuring RRAS to publish only one IP in DNS/WINS. This troubleshooting page may help,
