I have been getting complaints from my users about VPN connections dropping after an hour. All of my users are using laptops. Some are VPN'ing into there laptops from another system and others are using them to vpn out but the problems are similar. After about an hour they all lose connection to the system or network resources. I first thought this was a VPN issue so I asked our Network admins to look into it. They have told me that it as nothing to do with the VPN's setup. Are there any setting in Windows 7 Pro that would kill network connection over VPN after x amount of time? or could this be something else? any help would be appreciated.

Hi, This is a simialr problem that I had recently had and chased the problem for a month. I looked at the common areas (MTU settings,different VPN client and connectivity). Eventually parallel ran another make of firewall on the site and it worked OK with no drops. Turns out the problem was with my Checkpoint firewall and support for the Windows VPN client. Turns out checkpoint re-negotiates every hour and the client and firewall starts negotiating on different encrpytion and hence it drops. Installed the Checkpoint vpn client and have had no problems since. Hope this helps

I checked with our VPN folks and it doesn't seem to have anything to do with the client or VPN itself. I also looked into a domain policy but since it is only happening to one type of system I didn't find anything. Is there any typ of settings locally that could be causing this? Like a reg key or Windows 7 setting I don't know about?

Hi, Windows should not end the VPN session without any notification, I suggestion that you may check the VPN Connection Properties as following: Also I want to know the VPN type and authentication type. Since this problem occurs on many users in your company. I still suspect this problem is caused by the setting on your VPN server.
