While using Sonicwall Global VPN Client to connect my laptop to the office (SBS 2007), I frequently lose access to my mapped drives and get the "the local device name is already in use" message, even though the Sonicwall Client shows "connected". I can get them back by disable/enable, but that is time-consuming and frustrating. Drives are mapped by a login script when we log in to the domain. Sonicwall client is configured to run login script upon connecting.
Also, Outlook loses it's connection to the Exchange server.
I have the lasted NIC drivers, my laptop is a Dell. I suspect the Dell ControlPoint Connection Manager, but just because it's so inscruatable to me.
