HELP VPN NIGHTMARE!!!

[Guest]

I have several stores that vpn into the main store, most store can run for days on end with a vpn issue, other stores everyday we have vpn issues where they cannot connect giving erro 781-691-721 etc
Here's our setup. I have a mina store with a T-1 line and a backup dsl line coming in for the remote stores, they come into a nextlan router that can handle 2 broadband connections, then it goes to our server. Each store has a Main t-1 and a Backup vpn session on thier desktops. We have them connect to the Main t-1 1st and use that, if they cannot connect to it they need to use the backup. Sometimes that still don't work and if they try their T-1 they can get back on. There are about 15 remote connections coming in this way. Just about every day we have a vpn issue at one or another remote and I need to try and figure out a way to stop these errors. Does anyone have any idea why I am having this kind of problem? Am I running too many Vpn sessions into the router? MS can't handle it ? Any ideas I am willing to try..
Thanks in advance
Craig

It sounds like you are running Remote Access VPN instead of Site-to-Site VPN
(Router-to-Router), so you end up with a separate connection for each user
rather than a single connection per store. You would be better off with
Site-to-Site VPN but that will be complicated (if not impossible) with your
"duel line" setup. You probably have to run this by the people who built the
device you use the receive the connections and explain to them how you
implemented it. There are many types of VPN and most are proprietary to the
hardware vendor in varying degrees. You always have to do things "their
way" according to how they designed the equipment.

Below is a listing of what the error codes mean.

MS Remote Access can handle a lot more sessions that what you use. Are you use l2tp?
Error 781 is because a valid machine certificate is not found which would be needed
for l2tp. If you are not using l2tp, which would require a W2003 vpn server and nat-t
on the clients since you are going through a router, try configuring the clients to
use pptp in network type of the vpn connectoid. W2K/XP Pro will always try l2tp first
if the setting is auto. --- Steve
