WMI 'Access Is Denied' Exception on XP SP2 even with firewall off

WMI StopService 'Access Is Denied' Exception

The problem is that when I try to start/stop a service using WMI providers
on a remote machine (in this case one running embedded XP SP1, although I
don't think the flavour of XP matters) from an application on system running
Windows XP SP2 , I get the exception 'Access is Denied'. This is even with
the firewall turned off. This worked fine prior to installing SP2

We first started to notice this with an in-house application after
installation of XP SP2. However it can be demonstrated using the project on
the following website:

http://www.codeproject.com/csharp/wmi.asp

I've been able to get this WMI application to run successfully on XP SP2
(after enabling the remote administration services) except that when I go
into the Services tab and connect to a remote machine, although I can see the
full list of services on that machine, I cannot start or stop any of these
services (by right-clicking on the service to be stopped) without getting the
'Access is Denied' exception. I have tried logging in to the remote machine
as both a local user (that has full administrator privileges) and as
administrator. This application is working OK in SP1 and Windows 2000 systems
without any problems.

Any help greatly appreciated.
