Symptoms and Causes of Ad Error 1311
SYMPTOMS:
1. Error message: “Error 1311. Source file not found” when attempting to troubleshoot Active Directory error 1311 with NTDS KCC.
2. Inability to establish connectivity between directory servers in different sites.
3. Event ID 1311 in the event log indicating issues with directory service replication.
4. Error messages related to KCC errors and directory replication.
5. No logon servers available for domain controller.
CAUSES:
1. Connectivity issues between directory servers, potentially due to network problems or misconfigured site links.
2. Errors in the replication topology, such as incorrect naming contexts or domain trust issues.
3. Patching or updates applied to Windows Server without proper consideration of Active Directory dependencies.
4. Problems with the NTDS KCC (Knowledge Consistency Checker) algorithm responsible for generating the replication topology.
To troubleshoot Active Directory error 1311 with NTDS KCC, follow these steps:
1. Check connectivity between directory servers using the dcdiag command.
2. Review event logs for any relevant event IDs or error messages.
3. Verify the replication topology and correct any errors or misconfigurations.
4. Ensure proper domain trust is established if applicable.
5. Consider patching or updating Windows Server with caution, taking Active Directory into account.

Resolving Active Directory Replication Failures
To resolve Active Directory replication failures related to Error 1311 with NTDS KCC, follow these steps:
1. Check connectivity: Ensure that there are no network issues between the domain controllers (DCs) in different sites. Use the dcdiag tool to test connectivity.
2. Verify DNS configuration: Make sure that the DNS settings on each DC are correctly configured and that the DCs can resolve each other’s names.
3. Review site links: Check the site links configuration to ensure that they are correctly configured and that the replication schedule is appropriate.
4. Monitor event logs: Look for any relevant events in the event logs, specifically Event ID 1311 with source “NTDS KCC.” This will provide more information about the issue.
5. Run the Knowledge Consistency Checker (KCC): Use the repadmin /kcc command to force the KCC to recalculate the replication topology.
6. Troubleshoot any identified issues: Address any errors or warnings found during the KCC process, such as naming context errors or missing DCs.
Troubleshooting Site Link Bridging and Network Routing
If you are experiencing issues with site link bridging and network routing in Active Directory, specifically related to error 1311 with NTDS KCC, follow these troubleshooting steps:
1. Check the event log for any related errors or warnings.
2. Verify connectivity between domain controllers in different sites.
3. Use the Directory Service event log and Eventtracker tool to gather more information.
4. Ensure that the necessary naming contexts and directory partitions are properly replicated.
5. Investigate any events related to the root cause of the error.
6. Test the network routing between sites using tools like ping or tracert.
7. If the issue persists, consider contacting Microsoft support for further assistance.
Remember to address any specific error messages or symptoms you are encountering.
