RRAS setup for PPTP gives server 2nd IP address in DNS

Server 2008 R2 setup as a DC (small company only 1 server), configured RRAS for VPN via PPTP.  Connects, works great, however, getting reports that clients inside the network cannot access the server.  I find in the DNS that there is a 2nd IP address assigned to the server.  I delete the 2nd DNS record and the internal clients can reconnect to the server.  When I connect to the VPN and ping the server name, it replies with the proper IP address

Did I miss a step in the setup process to tell the RRAS to use the statically assigned IP address for the server?

I have tried restarting the RRAS.  Disabled and reconfigured the RRAS, same results.

This is an old problem that supposedly doesn't affect Windows server 2008, but still I have run across it occasionally when using RRAS with PPTP.  It has to do with the RRAS connection's IP address being automatically registered in DNS.

See if any of these methods fix the problem for you:

Found that the issue was due to the client had a PC that was not joined to the domain and was using the server for DNS and occasionally would access the server with that PC.  Resolved by hard coding the server IP in the host file.
Thanks for taking the time to respond.
