Dial Up Networking Error 800
Unable to establish the VPN connection. The VPN server may be un-reachable, or security parameters may not be
configured properly for this connection.
Pretty Generic VPN error..
There are a number of reasons to get this error. First thing to note, this error is a Microsoft VPN (pptp) error, not
a Cisco VPN or Lucent VPN or any other vendors VPN error.
1) The server in question might have an issue (down, rebooting, to many users on it). Suggest take a minute, surf to
some other safe sites (google, yahoo, etc..) If everything works but the VPN, grab a coffee and try again in a few
minutes, if it persists, email/call your helpdesk to check on the health/status of the VPN server. If you CANNOT surf,
then check your connection to the internet, remember if you can't connect to the internet, you won't be able to connect
over the internet to your companies VPN server.
2) Were any settings changed into your VPN connection? Did you accidentally change rom PPTP to L2TP? If you have
documentation on the correct connection settings, doublecheck to make sure nobody accidentally clicked something that
shouldn't of been clicked.
3) Any router or firewall changes recently? Might seem routine swapping out the firewall/router for a newer bigger
one.. but the rules/TCP/IP ports that were open on the last firewall/router might not of been opened on the new one..
