You have a system Centre 2012 R2 Configuration Manager Service Pack1 (SP1) deployment. You have two configuration baselines named CB1 and CB2 has a configuration item that verifies whether Remote…

In Configuration Manager, a configuration baseline cannot be deleted while it is referenced as an evaluation condition by another baseline. Since CB2 uses CB1 as an evaluation condition, that reference creates a blocking dependency. Removing CB1 from CB2's evaluation conditions eliminates the dependency and allows CB1 to be deleted.

Removing CB1 from deployed collections only removes its assignments to devices; it does not resolve the dependency that CB2 has on CB1 as an evaluation condition.

Modifying the configuration item inside CB1 does not affect whether CB2 references CB1 as a dependency, so the blocking relationship remains.

CB1's own evaluation conditions are unrelated to CB2's reference to CB1; changing what CB1 evaluates does not remove CB2's dependency on CB1.
