Why does the software disable Fast User Switching when you install VPN Client 3.1 on Windows XP?
A. Microsoft automatically disables Fast User Switching in Windows XP when a GINA.dll is specified in the registry. The Cisco VPN Client installs the CSgina.dll to implement the “Start Before Login” feature. If you need Fast User Switching, then disable the “Start Before Login” feature.
