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 220.127.116.11 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.

Port 47 (tcp or udp) has nothing to do with VPN. At some point in the past, the remote PCs were successfully logged onto the domain, so now log into that (but obviously can't connect).

the error says that to solution SolvedLaptop suddenly doesn't work anymore? We don't think that it's authentication; it doesn't seem to get that far. This doesn't explain why I could still somehow log onto the server from work, or why I couldn't log onto the router endpoint at the remote site, but I don't care But you do not need tcp port 47. > > > > > > Best wishes, > > > Bill > > > > > > "Frank" <> wrote in message
