Summary
In this module, you learned how to perform advanced Group Policy troubleshooting. You learned how to trace policy from definition, scope, inheritance, filtering, and domain-controller discovery through AD DS and SYSVOL retrieval, client-side extension processing, effective Windows state, and application behavior. You learned RSoP analysis, event correlation by Activity ID, AD DS and DFSR replication, timing and network dependencies, security-hardening compatibility, automated evidence collection, and integrated diagnostic cases. You learned to preserve evidence, compare healthy peers, test one hypothesis at a time, make the smallest safe correction, and validate policy delivery separately from the resulting system and application behavior.
