Hi guys
On a SBS domain, some of the workstations now have a Z: that wasnt there last month .
This Z: ONLY contains a sync/mirror of the users tmp files  (Appdata\Local\Temp\),
and the Z: shows in my Computer as the same size as the only HD C:

Disk management shows no Z: (Z isnt in Disk management)
Its not a mapped drive, it doesnt show in 'net use'. I have no idea how/why its now there
Any ideas ?
