This is easiest to do from another WinXX machine since all of the libs are
"just there." One really cool set of tools, UserInfo and UserDump, are at,

  http://www.hammerofgod.com/download.htm

These work even if the null user has been restricted. The author, Thor, had
some really fun talks at DEFCON.

A UNIX-based tool I've used is 'nat' (a.k.a. 'nbaudit') from,

  ftp://ftp.secnet.com/pub/tools/nat10/

But I don't think it works against systems where the null user has been
restricted. However, it is simply busy-work to reverse-engineer the 
WinXX-based tools to run on a UNIX-like system like Linux. I am not sure if
this has been done.
