When I take command prompt in XP or 2000 workstation, change to some network drive and directory and give command
ndir /spa
I get information about the space restrictions (quota) in that directory.

But if I give the same command in Windows 7 workstation I get
NDIR-4.27 (000519) PTF-909: You are not mapped to the specified drive. ().

Does anyone know, what that message means?
