AD KCC Error
I have Active directory 2008 R2 and I am seeing this errors on only one domain controller. I checked some forums that indicated objects no longer in use and found some in Sites and Services. I waited 24 hrs but still getting the errors. Has anyone ran into these errors and what would be the cause? Here are the errors/warning:
