My VPN times out after 5 min of inactivity. I connect to my companies PPTP- VPN and then start outlook. It will time out after 5-10 min. I had to reformat my HD because of other PROBLEMS.
Then the trouble started. It doesn't happen with internet connections. It also happens when I travel, so I know it's not my router or modem.
I have a IBM T41 laptop with XP. It has an internal "b" WIRELESS network modem. 256K
I reformatted again, exact same problem.
My companies IT dept went through the computer and couldn't find anything wrong.

Thanks for any suggestions!

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters.  In the RIGHT pane, find Autodisconnect and change the time accordingly.

Or...

Start/Run/net config server /autodisconnect:30 (30 being an example).  The valid value range is -1 to 65535 minutes at the command line. To disable Auto-Disconnect set it to -1.  Setting Autodisconnect to 0 does not turn it off and results in very fast disconnects, within a few seconds of idle time. (However, the RAS Autodisconnect parameter is turned off if you set it to a value of 0.)Many Thanks- your solution worked.
