Client Access Express Remote Command service not working

["Steve Landess" <steve_landess@xxxxxxxxxxx>]

Background:
I'm using V5R1 on a 170.  I just downloaded and installed the latest PTF's
on my AS/400 last week - C3175510 (3175), dated June 23, 2003.  I am running
the latest CAE service pack (SI08389) on my laptop under Windows XP Pro,
SP1.

While trying to start the Client Access Express Remote Command service, I
received the following error messages:

1) When this service is set to logon as a  local system account -
    Error message:
        Problem while starting Client Access Express Remote Command service
on Local Computer.
        Error 1313: A specified privilege does not exist.

2) I then tried using the administrator account for this service -
    Error message:
        Could not start the Client Access Express Remote Command service on
Local Computer.
        Error 1314: A required privilege not held by the client.

I saw mention somewhere (maybe in the archives) that by specifying "Allow
service to interact with desktop" helped another user get it started, but
this didn't work for me.

How do I find out what privileges are needed by whom in order for this
service to work properly?

Thanks for any insight,
