Under any decent OS you'd simply stat() the files and
compare inodes, under DOS and its PTFs this is one of the most
intreaguing and challenging problems. Give your
masochistic side a chance and look at stat.c to see
to which pains it goes to find out if something is local or
on a networked drive. 

For your particular setup, truename() ( _truename() ?)  
might be a solution, because WfW mapped drives and
NetWare drives (when using VLM) are converted into
\\server\path\file, regardless of mapping (Maybe with a 
bit of \ => / or vice versa, to make things not too easy).
