 Trouble with LogonUser API

Hi All,
I'm having a problem with LogonUser and ImpersonateLoggedOnUser.
Basically, I'm trying to create a directory while impersonating a user.
This will give ownership of the directory to that user that I've logged
in as in my code.  I'm open to other suggestions as to how I can give
ownership to a particular directory.  Anyway, the below code works fine
on a PDC.  However, when its run on a client machine running NT Server
4.0 (not the PDC), I get the error 1314, A required privilege is not
held by the client.  Now I'm sure I've assigned all the required
privileges to the client, "Act as part of Operating System" and all the
rest.   In fact, I've granted every privilege in the list to the logged
in user running the code below.  I still can't get it to work on the
client machine.

Any help is much appreciated, Thanks,
Tony Stroessenreuther
