Slow reaction since I didn't find time for this over the last weeks.

Only in case of drive-mappings of your own system this happens.
If I map my home-directory (c:\data\geert) to z:\
Then z:\ and c:\ are definitely different directories.
But emacs (file-attributes) returns: (t 2 5 5 (0 0) (0 0) (0 0) 0
"drwxrwxrwx" nil 0 (62622 . 44923))
In *both* cases!
However for c:\data\geert it returns: (t 2 5 5 (16258 51768) (16258
51768) (16187 28471) 0 "drwxrwxrwx" nil 0 (62622 . 44923)).

File-truename returns: c:/ and z:/ respectively, so that doesn't help.
I can't see if Windows returns bogus or that emacs is wrong.

And there is also question 2 left: 
Emacs says t in respons to (file-exists-p "").

Isn't that very strange??

  I'm surprised by that, given the following remarks in the

11. The file's inode number. If possible, this is an integer. If the
number is too large to be represented as an integer in Emacs Lisp, then
value has the form (high . low), where low holds the low 16 bits. 
12. The file system number of the file system that the file is in. This
and the file's inode number together give enough information to
distinguish any
two files on the system--no two files can have the same values for both
these numbers. 

Are you saying that NT emacs just returns bogus information for these
"attributes" elements?
  Have you tried file-truename?
