Windows Explorer slow to open with Disconnected Network Drives

[Guest]

Hello everybody,

A bunch of my mobile clients are having issues with Windows Explorer and
Open File Dialogs being annoyingly slow when they are not connected to our
network and their persistent mapped drives are not available. I know that
there is a group policy setting out there that says not to wait on these to
open, but I can't find it. Is anybody out there able to shed a little light
on the subject?

Thanks,

Jim Jones
