Routine Description:

    Queries if the machine is a server or workstation via
    the NetServerGetInfo API.

Arguments:

    Server - The machine to query, or NULL for the local machine

    DomainControllerFlag - Receives TRUE if the machine is a
                           domain controller, or FALSE if the
                           machine is a workstation.

Return value:

    TRUE if the API was successful, or FALSE if not.  GetLastError
    gives failure code.
