UAC Effects Access to Mapped Drives
If a network share is mapped to a drive letter from within an elevated process, GetLogicalDrives called from a non-elevated process will not see the mapped drive. That seems somewhat logical. Conversely, a network share mapped to a drive letter from within a non-elevated process will not be seen by an elevated process calling GetLogicalDrives. This is very unexpected. Other drive related functions like GetDriveType also exhibit this peculiar behavior.
