I am connecting to our corporate domain by VPN over a RAS connection through an aircard or a tethered connection. I am having some difficulties getting Windows 7 to preserve the RAS connection during the logoff phase. The KeepRASConnections registry doesn’t appear to be working in windows 7. On my Windows XP workstation I edit the KeepRASConnection registry key to 1 and I can log off and log back on and the connection persists. I tried the instructions in this KB article: http://support.microsoft.com/kb/950918 The instructions in this article didn't work in Windows 7. Would there be a workaround in Windows 7 to keep RAS connections alive during log offs and logons?

The key mentioned in the article is already present and properly configured in Windows 7. Therefore it should not be the problem. I suspect that the network adapter is turned off in Sleep Mode. You may change it in Device Manager. In Device Manager, open the “Properties” for the network adapter. Then in Power tab, uncheck the option "Allow computer to turn off this device to save power". If the issue persists, I suggest you upgrade your BIOS.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Thanks for the reply. When I tether a device like a Blackberry it is basically a dial up connection that you have to create. Once the connection is established, the VPN software is launched and the VPN software is configured to log the user off of the session. The user then has to log back on using their domain username and password. This ensures proper logon to our domain (scripts running to map drives etc.). With a wireless connection this isn't a problem as Windows 7 "remembers" the connection. But with a dial up connection (tethered) it disconnects when the VPN software logs the desktop off. In Windows XP changing the KeepRasConnections key to 1 always preserved the dial up connections during log offs and logons. In Windows 7 if you change they key value to 1 it doesn't preserve the dial-up connection during log off/ log on.
