That looks promising indeed. On closer reading I can see, that
works only on the server:

   Requirements
   Client 	Requires Windows XP, Windows 2000 Professional, or
                 Windows NT Workstation 4.0 SP3 and later.
   Server 	Requires Windows Server 2003, Windows 2000 Server, or
                 Windows NT Server 3.51 and later.

   Library 	

   Link to Advapi32.lib.
   DLL 	Requires Advapi32.dll.

(I couldn't find Advapi32.lib on my XP-machine)

For my purpose that is good enough (I think), but I'd love to know
how to do it on a client.
