If you are using a SLAC-issued centrally-managed Windows laptop, and you don't see your network drives after connecting to the VPN, you can connect to all these drives by running this script: \\slac.stanford.edu\netlogon\domainlogon.vbs. It should be possible to create a shortcut or bookmark to this script to make it easier to connect to network drives.
If you are using a personal machine not in the SLAC domain, then domainlogon.vbs does not work. You will need to map your drive manually using http://www2.slac.stanford.edu/comp/net/dialup/faq-dialup.htm#map.
What are the timeouts on the VPN connection?
