DNS_ERROR_NO_DNS_SERVERS

No DNS servers configured for local system.

DNS_ERROR_NO_DNS_SERVERS is Windows status 9852 (0x0000267C) associated with local resolver configuration with no DNS server addresses. The system meaning is “this condition” Preserve the value at the API boundary because subsequent cleanup or logging calls can overwrite the last-error state.

Operational meaning

The key question is whether at least one appropriate DNS server is configured and reachable for the active interface. The value describes local resolver configuration with no DNS server addresses; it does not prove that the whole domain, DNS service, network, servicing stack, application package, or operating system has failed.

Likely impact: Applications may report unrelated connection failures until resolver configuration is restored. Record the scope that was actually tested instead of escalating from one rejected object or phase to a system-wide outage.

Where the result appears

  • This result can appear while processing local resolver configuration with no DNS server addresses.
  • This result can appear while a DNS Server API request that validates a zone, record, property, or server setting.
  • This result can appear while a dynamic update, zone transfer, WINS integration, or reverse-record workflow.
  • It can appear while a management script or DNS console operation translated to a Win32 DNS status.

Typical causes

  • DHCP did not supply DNS servers.
  • static adapter configuration is incomplete.
  • VPN or policy removed resolver addresses.
  • the active network profile uses the wrong interface.

Diagnostic sequence

  1. capture it immediately after the failing or status-returning call and record whether the API uses Win32, DNS_STATUS, HRESULT conversion, or callback semantics.
  2. identify the exact target involved in local resolver configuration with no DNS server addresses, including stable GUIDs, DNs, zone names, package identities, file hashes, policy names, or process identifiers as applicable.
  3. prove the state boundary: at least one appropriate DNS server is configured and reachable for the active interface.
  4. collect Get-DnsClientServerAddress output and active interface and route before restarting services, deleting objects, rebuilding packages, or changing policy.
  5. correlate DHCP lease or static settings with the DNS Server event log, DNS analytical logging when enabled, packet capture, zone metadata, server configuration, and the exact DNS API request.
  6. determine whether the result is a failure, warning, informational completion, continuation request, or marker constant before choosing retry behavior.
  7. after changing one responsible condition, repeat the same smallest operation and verify both success and absence of unintended partial effects.

Evidence to preserve

  • collect Get-DnsClientServerAddress output.
  • collect active interface and route.
  • collect DHCP lease or static settings.
  • collect VPN and NRPT policy.
  • collect reachability to proposed DNS servers.

Correlate this evidence with the DNS Server event log, DNS analytical logging when enabled, packet capture, zone metadata, server configuration, and the exact DNS API request. Preserve raw identifiers and the first detailed diagnostic: translating everything to 9852 can hide whether the cause was validation, topology, authorization, replication, policy, file I/O, packaging, or an intentional continuation state.

Recovery and retry

The recovery objective for it is to configure valid DNS servers for the active network path and verify queries against them before retrying the dependent operation.

Retry only after the recorded boundary changes and prior completion is known. Read-only discovery for it can usually be repeated with bounded backoff; directory mutations, DNS updates, policy installation, servicing actions, and PRI writes require a state check first. Backoff for it cannot repair malformed input, unsupported structure, identity collision, missing authority, or incompatible package metadata.

Telemetry and support fields

  • record error_no_dns_servers_operation — producing API, command, callback, or servicing phase.
  • record error_no_dns_servers_target — stable object, zone, policy, package, file, or account identity.
  • record error_no_dns_servers_state_before and error_no_dns_servers_requested_state.
  • record error_no_dns_servers_first_status — earliest component-specific code before translation.
  • record error_no_dns_servers_server, error_no_dns_servers_process, UTC timestamp, and correlation ID.

A support bundle for it should include decimal 9852, hexadecimal 0x0000267C, the smallest reproducible request, target identity, effective configuration, and evidence from the owning Windows component. When documenting it, remove secrets from exported logs but keep SIDs, GUIDs, package-family names, record types, and hashes when they are needed to distinguish objects.

Difference from nearby results

DNS_ERROR_NO_TCPIP means the protocol stack is unavailable; this code means the stack exists without resolver servers This distinction determines whether the correct next step is input correction, topology repair, continuation, policy review, package rebuild, or no error handling at all.

Practical validation scenario

A VPN connection replaces adapter settings with an empty DNS list. Restoring the intended tunnel DNS servers makes domain lookups succeed. A negative test should reproduce it with the responsible condition preserved; the recovery test should alter only that condition and confirm the intended final state.

Developer and administrator guidance

Developers should model it explicitly in the result domain instead of collapsing every nonzero value into “failed.” Administrators should capture evidence before destructive remediation and use the component that owns local resolver configuration with no DNS server addresses. Monitoring for it should suppress range markers and classify warning, informational, cancellation, and continuation values separately from terminal failures.
