DNS_WARNING_PTR_CREATE_FAILED
Could not create pointer (PTR) record.
DNS_WARNING_PTR_CREATE_FAILED is Win32 error 9715 (0x000025F3).
Likely impact: Name-to-address lookup can work while reverse lookup, auditing, and services relying on PTR records remain incomplete.
Typical causes
- no reverse zone exists.
- the reverse zone is not writable by the updater.
- delegation or credentials block the update.
- the IP address maps to a different reverse namespace.
Troubleshooting steps
- Verify that the forward record can be paired with a writable authoritative reverse zone and valid PTR target.
- Collect forward record result and IP address and expected reverse owner name.
- Correlate reverse-zone authority and ACL with the DNS Server event log, DNS analytical logging when enabled, packet capture, zone metadata, server configuration, and the exact DNS API request.
Useful evidence
- Collect dynamic-update response.
- Collect existing PTR values.
Recovery and retry
Keep the successful forward result, repair reverse-zone authority or permissions, and create the PTR separately if policy requires it.
Related errors
A DNS_ERROR value may mean the primary operation failed; this warning can accompany a successful forward record with missing reverse data
Example
A DHCP update creates the A record but lacks rights in the reverse zone. Delegating secure update rights restores PTR creation without rolling back the forward record.
