Installing OMSA 6.1, problem configuring WMI user authorization.

Hello. In the guide to install OMSA 6.1 on Windows under "Configuring User Authorization for WinRM and WMI Servers" there are two steps:

4. Click Security and expand the Root node in the namespace tree.

5. Navigate to Root -> DCIM -> sysman.

I've expanded "Root" but can't find another "Root" or a "DCIM" branch found under it.

This is on a 32-bit Windows Server 2003 Enterprise Edition SP2.

Are these steps necessary to get OMSA / Remote Enablement to work?
