I'm in the process of implementing the Beta of SCOM 2007 R2 at work and had some SCW work to do on the servers that are going to run the SCOM Agents. I found this useful link which has the XML manifest for SCOM 2007, allowing easier configuration of the various SCOM 2007 components using the Security Configuration Wizard.
