It is not recommended to enable RRAS on a DC, otherwise, you
may have a connectivity issue. One option is reconfigure the DC to block PPTP
register on the DNS and WINS. this link may help,
I'm
trying to setup a VPN in my office server and encountered some problems. We
have one windows 2000 server which also serves as a domain controller with
a fixed ip address (192.168.1.8). This server can access the internet
without problem through the firewall. We have about 10 workstations each
has a fixed ip address. The DNS server for each of the workstation has the
domain controller (192.168.1.8) as the preferred dns server, then the ip
address of the dns server for internet service as the alternate dns server
(209.53.4.120). I was trying to configure Routing and remote access in our
W2K server (with the wizard) to use VPN. In the internet connection screen
in the wizard, I selected 'no internet connection'. In the IP
address assignment screen, I selected 'automatically' and no radius
server.
At home, I configured the Win XP pro to connect to the office
server. However, every time after I had made a successful connection to
the office from home via VPN; if I looked at the DNS screen, I saw that
in the forward lookup screen, my domain controller actually got two
ip addresses, i.e. the 192.168.1.8 (original fixed ip) and one extra
ip address (e.g.192.168.1.125) assigned to it. I was then not able
to connect to the internet in the server computer (also the
domain controller). Also, all other workstations had problem printing to
a network printer and no longer able to ping the server.
I'm
pretty inexperienced in network administration and your help is greatly
appreciated.
