AD-SITE-04 - Sites without subnet associations count should be retrievable
Overviewβ
Sites without subnet associations cannot be used for client site assignment:
- Authentication inefficiency: Clients may authenticate to distant DCs
- Replication issues: Site topology may not reflect actual network boundaries
- Configuration gaps: Sites may have been created incompletely
- Client confusion: Computers cannot determine their site membership
Every site that should be used for client location must have at least one subnet assigned.
Security Recommendationβ
- Assign appropriate subnets to all production sites
- Remove sites that are no longer needed
- Ensure subnet assignments accurately reflect network boundaries
- Review site-subnet mappings during network changes
How the Test Worksβ
This test analyzes subnet-to-site associations to identify sites that have no subnets assigned to them.
