Windows 2008 WMI Access Denied

Windows 2008 WMI Access Denied

When trying to setup OpManager to monitor a Windows Server 2008 in our DMZ, it keeps coming back with an access denied.
 
I can used WBEMTEST to connect to the target server - confirming that the target server is configured properly and that no firewalls are blocking anything.
 
I can also run the cpu.vbs script in \conf\application\scripts and get a valid connection.  I can run the list_services.vbs script and get the list of services.
 
But, I can't get OpManager to connect using WMI.
 
Any ideas what I should be looking at?
 
Thanks,
-Joe
