Kevin,

This is great but it stills requires the manual creation of groups for very possible registry key.

What we are exploring right now is how to create a dynamic group and scoped role based on different string values of defined registry keys.

Say a registry key contains the name of the business group who owns the server. Lets say say the value is SupportTeamX. This registry key will be read by OpsMgr, create a computer group called SupportTeamX and create a scoped role called SupportTeamX that is scoped to just that computer group.

Active Directory group membership of the role can be managed separately.

Would you have any examples of something like this? Based on the work so far I think the dynamic group and role creation is going to require managed code to handle.

Kevin, how should we convert a formula to scom that uses boolean conditions (Check if exists). It doesn't seem to have an option in SCOM for that. Should we use "Equals True", like below for example?

( Object is Windows Server Operating System_Extended AND ( MOSS 32bit Equals True )

You nailed it - that is exactly correct - as I am sure you found out by testing. Boolean or "check if exists" will always be "attributename" equals "true"

Firstly thanks for a great easy to follow example but I still have a few issues to make this work with clusters.

Is there anyway for the support value of the underlying cluster node to be set for the virtual nodes it hosts?

They are discovered by the extended class but the supportlevel is always blank. Which of course means if you use these groups to limit for example to level 1 SQL DB Engines then any SQL instances on a cluster are missing.
