DNS_ERROR_NO_BOOTFILE_IF_DS_ZONE - 9719 (0x25F7)

DNS server not creating or reading the boot file for the directory service integrated DNS zone.

Updated: Feb 21, 2026

Technical Background

The DNS_ERROR_NO_BOOTFILE_IF_DS_ZONE error code, with the numeric value of 9719 and hexadecimal representation 0x25F7, is encountered when a Windows DNS server fails to manage the boot file for a directory service integrated DNS zone. This error typically indicates an issue related to the integration between Active Directory (AD) and DNS.

Error Details

This specific error code is associated with the capability of the DNS server to interact with AD for managing DNS zones. The boot file, which contains critical information about the zone's configuration, must be properly managed by the DNS server to ensure the zone functions correctly within the directory service environment.

Common Causes

  • Incorrect Zone Configuration: The DNS zone may not have been configured as a directory service integrated zone, leading to the failure in managing the boot file.
  • AD Integration Issues: There might be problems with the integration between AD and the DNS server, preventing it from accessing or updating the necessary files.
  • Permissions Problems: Insufficient permissions on the DNS server or within AD could prevent the necessary operations from being performed.

Real-World Context

In a Windows environment where DNS zones are integrated with Active Directory for centralized management, this error can occur if there is a misconfiguration or an issue with the interaction between these components. This often results in the inability to properly manage and update DNS zone information within AD.

Is This Error Critical?

The criticality of this error depends on the specific use case. If the affected DNS zone contains critical records, such as those for domain controllers or other essential services, then the issue could have significant implications for network functionality and security.

How to Diagnose

To diagnose the DNS_ERROR_NO_BOOTFILE_IF_DS_ZONE error, follow these steps:

  1. Review AD Integration Settings: Ensure that the DNS zone is correctly configured as a directory service integrated zone in Active Directory.
  2. Check Permissions: Verify that the DNS server has the necessary permissions to read and write to the boot file within AD.
  3. Validate AD Connectivity: Confirm that there are no issues with network connectivity or AD replication affecting the DNS server's ability to interact with AD.
  4. Review Event Logs: Check the DNS server event logs for additional error messages that might provide more context about the failure.

How to Resolve

To resolve this issue, consider these practical steps:

  1. Correct Zone Configuration: Ensure that the DNS zone is properly configured as a directory service integrated zone in AD.
  2. Adjust Permissions: If necessary, adjust the permissions on the DNS server or within AD to ensure it has the required access rights.
  3. Check Network Connectivity: Verify network connectivity and AD replication status to ensure there are no issues affecting the interaction between the DNS server and AD.
  4. Restart Services: Restarting relevant services such as DNS Server, Netlogon, or Active Directory Domain Services might help resolve transient issues.

Developer Notes

When encountering this error, developers should focus on ensuring proper configuration of directory service integrated zones and verifying that all necessary permissions are correctly set. Additionally, monitoring event logs for related errors can provide valuable insights into the root cause of the issue.
