I set up a VPN server on a Windows Enterprise Server 2003 64bit, and got it running with full functionality. Ever since then there are now 2 entries for that computer in the DNS records. This is causing problems with my users who access the computer for other reasons on the network. When they try to connect, often their computer is trying the wrong IP address (the one for the VPN connection), instead of the original IP of the computer.

Is there a way to make VPN work without creating the second IP address? Or is there a way to make it so other computers will connect to the correct IP address of the server?

Thanks!

So do you have 2 interfaces on the server? One internal with a private IP and one external with a public or DMZ IP?

If so, the external NIC need not register in your AD DNS at all. So go into the TCP/IP properties of that NIC and go to Advanced / DNS tab and UNCHECK "register this connection ...". Make sure it removes the entry from your AD DNS or remove it manually.

Also, this NIC need not be a client or server so for security (in addition to your edge firewall), you can probably uncheck "File and Print Sharing ..." and Client for Microsoft Networks" from this NIC.

That seems to have done the trick. Thanks.
