why don't some WMI classes work?

I had a problem where the MSMQ data sources were not being displayed in the LogicMonitor portal. The following worked for me, run wmiadap /f.n

You might need to rebuild your WMI registry.n

nAlso if you want to completely just rebuild wmi run the winmgmt /salvagerepository command.n

nThe above command performs a consistency check on the WMI repository, and if an inconsistency is detected, rebuilds the repository. The content of the inconsistent repository is merged into the rebuilt repository, if it can be read.
