SMALL BUSINESS SERVER 2003 PPTP VPN ERROR 800
Hello Experts!
One of our servers stopped allowing users to connect via PPTP last week and we have not been able to resolve. This has worked for over a year WITH the current configuration and nothing appears to have changed on any of teh devices??? When attempted the system gives us error 800. This is what we know so far...
Server is listening on port 1723
Server allows connections and telnet to 1723 internally
Netgear DG834 that is forwarding the port reports a success to the firewall rule via SYSLOG
This would obviously suggest a networking issue but we are currently trying to determine whether the problem lies inbound or outbound because the default gateway of the server is not the device that forwards the port. I have run wireshark on the server but have not yet found any evidence of PPTP traffic actually hitting the server (but I`m still looking in these results)
SETUP
REMOTE USER --- DG834 --- CISCO 1800 --- SBS 2003
DG834 is the Inbound IP address (that they point to for connection) which forwards straight to the server
Cisco 1800 is the server default gateway
DG834 is the Cisco's way out to the internet
Any suggestions? Remote Access wizard had no effect, server reboot had no effect!?
Thanks

I thought of this but did not really follow up on it because of the fact that internal connections work. I agree that with the server restart having no effect that some kind of "change" has happened. But again, because this works internally I cannot see how the server could change anything that would change the way external clients connect to it. I know that deep within the settings of RRAS there are routing elements and rules etc but surely re running the Remote Access Wizard over rides any current settings that could have changed?
I will check the updates and new installs as you have suggested because looking at a problem for too long makes you think in a funny way so you miss obvious things, -as I`m sure you know all too well!!
