DNS_ERROR_NBSTAT_INIT_FAILED
NBTSTAT initialization call failed.
DNS_ERROR_NBSTAT_INIT_FAILED is Win32 error 9617 (0x00002591) in Windows DNS client or DNS Server management.
Likely impact: Only workflows depending on legacy NetBIOS integration should be affected; standard DNS must be tested separately.
Typical causes
- NetBT is unavailable or disabled.
- adapter binding is inconsistent.
- WINS integration requests an unsupported path.
- the service cannot allocate or open the required NetBIOS context.
Troubleshooting steps
- Verify that the NetBIOS status component initializes with valid interfaces and legacy network support.
- Collect NetBT and adapter configuration and DNS and System events.
- Correlate zone WINS/NBSTAT settings 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 network protocol installation.
- Collect service initialization status.
Recovery and retry
Repair the required NetBIOS component or remove the legacy NBSTAT dependency, then reload the zone.

Example
A hardened server has NetBT disabled but an imported zone still requests NBSTAT behavior. Removing that legacy setting allows DNS startup.
