 Volume in drive \\root\share is Data
 Volume Serial Number is 0123-4567

 Directory of \\root\share

11/11/2011  12:34    <DIR>          BUILTIN\Administrators .
11/11/2011  12:34    <DIR>          BUILTIN\Administrators ..
               0 File(s)              0 bytes
               2 Dir(s)  123,456,789,000 bytes free

In cmd if the current directory is \\root\share then (just the same as
for c:\) "cd .." does not change directory and "dir /a:d ." and "dir
/a:d .." display the same thing.
