This is a key thing I'm curious about. How is drive mapping handled? If I "net use d: \\host\share" from one session, it won't nessarily translate and mount D: to all sessions (or will it)?
I can't check right now, but if you have two local users, Delta and Gamma, and Gamma mounts D:\, does Delta see it or is it specific to Gamma's session?
Drive letter mappings differ even between Delta and when Delta opens a command prompt as administrator.
Mapped network drives are for each user separately. Actually, they are even different for the limited administrator token and the elevated one (e.g. if I run something as administrator here I won't see my mapped network drives, but instead have to use UNC paths).
