Vpn Error 800 Fix
Status: offline Hi: Installed ISA 2006 on a domain controller running Windows server 2003 R2with 2 NIC's. 1st NIC on 192.168.0.0 network and second NIC on External network 196.26.91.0 and connected directly to CISCO router on Internet. Configured VPN access and can connect to VPN on internal network. Problem comes up when I try to connect from the Internet. I get an vpn error 806 Error 800: Unable to establish VPN connection. If I check logging on ISA server I can see PPTP port 1723 being opened from the client and then closed without any errors. I also see the client opening HTTPS ports. Got no idea why it would want to open HTTPS when connecting via VPN. I can also telnet toport 1723 from the internet. Any help will be appreciated. _____________________________Johan Grové Senior Technology Architect Cellphone 0825227200 MSN: johangrove@hotmail.com www.eclipse.co.za Post #: 1 Featured Links* RE: VPN Error 800 Unable to establish the VPN connection - 23.Jan.2008 2:54:02 PM elmajdal Posts: 6022 Joined: 16.Sep.2004 From: Lebanese in Kuwait Status: offline quote:Installed ISA 2006 on a domain controller No NO NO NONO Never Install a Firewall on a DC !!

A common issue encountered when working with virtual private networks is VPN error 800 - "Unable to establish the VPN connection." Unfortunately this error code doesn't explain why the connection is actually failing.What Causes VPN Error 800This issue occurs error 800 when trying to establish a new connection to a VPN server. It indicates that messages being sent by VPN client are failing to reach the server. Many possible reasons for these connection failures exist including:the client device has lost connection to its local networkthe user has specified an invalid name or address for the VPN servera network firewall is blocking the VPN trafficHow to Resolve VPN vpn error 800 Error 800Check the following to address any potential reasons for this failure:Is the network connection between client and server functioning properly? You can attempt to ping the server if not sure, although VPN servers can be configured to ignore ICMP requests.

The name a user enters on the client side must match the server name set up by a VPN administrator.  Given a choice, users can opt to specify an IP address instead of a name.

by side in a colo facility, one behind a firewall, one not. The one behind the firewall can connect just fine to the VPN server at another site, the exposed one CANNOT. If I reboot the exposed server, it can connect to the VPN server for about 2 weeks, then starts getting Error 800. A reboot clears it up. The exposed firewall has a much higher application load (both are running a web app with backend connection to a SQL server). I can telnet on port 1723 to the VPN server from both boxes. I believe an internal resource (like ports) are getting used up and not released....any way to prove that? netstat -a shows about 40 ports in use (connections to sql server).
