If it is a MS router, did you let it autoupdate itself? However, it doesn't like that, I have to use the router's IP (meaning I have to point ras2.mydomain.com to 208.38.4.101 in our DNS servers) and then forward PPTP to the RAS I and my colleagues are totally stumped - we know each end is fine independently, but for some reason they won't work together.
