PPTP VPN Conneciton Dropping

I have a SBS2003 setup with one client using his laptop that is already part of the domain to connection remotely via the included SBS VPN software. I create a new connection on his laptop and enable all users to use it so he can select it from the logon screen.

Anyway, the VPN connects fine, but he is always disconnected after anywhere from 10-30 minutes. Last time he was disconnected after 22 minutes. There is no timeout limit and it wouldn't matter anyway since he's active when he is getting kicked off the connection. He has to log off/log on to restore the connection. The connection is set to "reconnect if disconnected" but it just doesn't do so.

By the way, the router there is a Symantec Gateway Security 360.

Any ideas? I'm going over there tonight to sub out the router for a new one. I hoping that fixes the problem, but I doubt it.

Have you done any tests using the VPN connection from a different location?  I'm wondering if it's something at his end rather than the server end that is disconnecting him.

How is he connected at the alternative location? Wireless or wired? Is ther driver updates for the nics in the laptop? Is it fully patched and AV run on it?
Is the gateway up to the latest version of firmware?
Can you use the router to create a vpn connection instead?
Thank you,

Rather than manually configuring the VPN connection on the laptop, have you tried using the SBS Connection Manager (VPN Client)?  You would download this from the Remote Web Workplace main menu.

I've pretty much determined that the router was the problem. I replaced the Symantec Gateway Security 360 router/firewall with a consumer Netgear wireless router (http://www.newegg.com/Product/Product.asp?Item=N82E16833150022). Everything worked fine and it stayed connected the entire time.

So, yes the firmware on the 360 was fully upgraded. It it is a better router (I would assume...at 4 times the cost of the netgear). Is keeping the Netgear in there a bad idea? What could be wrong with the symantec firewall?

Basically if I can keep the symantec in there I would like to...otherwise is the netgear a bad choice?

The netgear isn't a bad choice... depending on what's important for you.

Check this out regarding the 360 though:  http://groups-beta.google.com/group/microsoft.public.windows.server.sbs/browse_thread/thread/ef3f0bec7f1f0268/5785ca6a3b8b9b63
