I just looked into this and I really don't see a way.  While there's a
NetUseGetInfo call, which is pretty fast even for unavailable drives,
it's not reliable.  Even if the drive is available again, it can take
minutes in which it still returns a status of "Session lost".  I'm not
sure this is what we want.
