We have a remote user who is getting this error message when trying to
connect remoyely to our corporate network: "Error 800 - Unable to establish
the VPN connection. The VPN server maybe unreachable or security parameters
may not be configured properly for this connection." I have had them disable
MS firewall and EZ antivirus, but still not success. They are using XP Pro
SP2. No other remote
users are experiencing this. Any ideas will be appreciated.
Thanks

Can you ping the VPN server? if yes, can you telnet the port 1723?

The VPN server is an ISA server 2004 and will not accept pings on the
external interface.
