Correct, and the DOS redirector, that Microsoft uses limits server names to
11 characters.  Just try addind a long name to NT, it will warn you about
the name length for compatibility with DOS.  Though I have never actually
tried using a DOS client with a long name, NT's GUI does complain that it
could happen.
