On Windows 2000 and previous releases, the PowerExchange Listener user ID must have the SE_TCB_NAME privilege. In User Manager, this privilege is the “Act as part of the Operating System” right. On Windows Server 2003 and later releases and on Windows XP and later releases, no additional Windows configuration is necessary.
