I'm deploying some fairly simple configuration baselines - most with a single CI in it; some remediate, some do not.
In all cases, the Compliance count (as found on the Assets and Compliance/Compliance Settings/Configuration Baselines page in the SCCM console) is roughly double the number it should be.
The same numbers can be found in the report: Compliance And Settings Management \ Summary Compliance by configuration baseline. In that report, however, you can drill into the individual baselines, which takes you to "List of assets by compliance state for a configuration baseline". I find that if I add up all of the assets from this report, the number is accurate.
We have about 4000 people in one of these CI baseline deployments, and it's showing about 8000 are compliant. We don't even have anywhere near that many clients. In another one, we have about 150 users and it's showing 280 compliant.
It just seems that the summarization data is somehow inflated, and completely inaccurate. Anyone know how that is calculated, or have you seen this before?
