FRS_ERR_INVALID_SERVICE_PARAMETER

The file replication service detected an invalid parameter.

Windows assigns decimal 8017 and hexadecimal 0x00001F51 to FRS_ERR_INVALID_SERVICE_PARAMETER. For FRS_ERR_INVALID_SERVICE_PARAMETER, the decisive subject is a parameter supplied to the legacy File Replication Service; the value alone does not reveal which object, server, file, session, or transition failed.

The native value for FRS_ERR_INVALID_SERVICE_PARAMETER is 8017 (0x00001F51). Preserve FRS_ERR_INVALID_SERVICE_PARAMETER immediately after the failing Windows call because later logging, cleanup, LDAP, RPC, or file operations can replace the last-error value.

Where this result appears

  • For FRS_ERR_INVALID_SERVICE_PARAMETER, processing a parameter supplied to the legacy File Replication Service.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, managing a legacy FRS replica set or SYSVOL member.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, handling a service, RPC, directory, staging, or database transition owned by NtFrs.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, running an administrative tool against an environment whose FRS/DFSR migration state must be known.

State boundary to prove

FRS_ERR_INVALID_SERVICE_PARAMETER applies to a parameter supplied to the legacy File Replication Service and does not by itself prove that the entire server, directory, disk, session, or application is unavailable. The state boundary to prove for FRS_ERR_INVALID_SERVICE_PARAMETER is whether the parameter type, range, identifier, and replica-set context satisfy the FRS API contract. Use API name and complete sanitized parameters, expected type and range, and replica-set/member identifiers as independent evidence. When evidence for FRS_ERR_INVALID_SERVICE_PARAMETER disagrees, preserve timestamps and investigate the transition instead of selecting the most convenient value.

Likely causes

  • For FRS_ERR_INVALID_SERVICE_PARAMETER, an identifier is malformed or unknown.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, a numeric value is out of range.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, a parameter belongs to another replica set.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, a null or stale context was supplied.

Diagnostic sequence

  1. For FRS_ERR_INVALID_SERVICE_PARAMETER, capture error 8017 immediately at the API boundary and record the operation that was attempted.
  2. For FRS_ERR_INVALID_SERVICE_PARAMETER, identify the exact owner of a parameter supplied to the legacy File Replication Service, including object generation, server, path, session, replica, or client context.
  3. For FRS_ERR_INVALID_SERVICE_PARAMETER, collect API name and complete sanitized parameters before restarting a service or changing configuration.
  4. For FRS_ERR_INVALID_SERVICE_PARAMETER, compare expected type and range with the documented or observed precondition.
  5. For FRS_ERR_INVALID_SERVICE_PARAMETER, correlate replica-set/member identifiers with the File Replication Service event log, Service Control Manager, Directory Service and Netlogon events, RPC diagnostics, and replica-set state.
  6. For FRS_ERR_INVALID_SERVICE_PARAMETER, determine whether side effects occurred and verify recovery after changing one responsible condition.

Evidence to collect

  • For FRS_ERR_INVALID_SERVICE_PARAMETER, API name and complete sanitized parameters.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, expected type and range.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, replica-set/member identifiers.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, service version and caller assumptions.

Correlate FRS_ERR_INVALID_SERVICE_PARAMETER with the File Replication Service event log, Service Control Manager, Directory Service and Netlogon events, RPC diagnostics, and replica-set state. Keep the first detailed status even when a later wrapper translates it to error 8017; the first status often distinguishes transport, authorization, storage, schema, state, and application-integrity causes that share the same final Win32 result.

Handling, retry, and recovery

For FRS_ERR_INVALID_SERVICE_PARAMETER, the recovery objective is to correct the caller input from current FRS state and retry from a validated context; service restarts do not repair an invalid parameter.

Retry FRS_ERR_INVALID_SERVICE_PARAMETER only after the recorded condition changes and completion state is known. For FRS_ERR_INVALID_SERVICE_PARAMETER, idempotent queries may be repeated after recovery, but mutations require a state check first; backoff cannot repair malformed input, corruption, missing structure, or policy rejection.

Telemetry and support fields

  • For FRS_ERR_INVALID_SERVICE_PARAMETER, record invalid_service_parameter_api for the producing function or management operation.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, record invalid_service_parameter_target for the file, log, session, replica, object, or server identity.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, record invalid_service_parameter_state_before and invalid_service_parameter_requested_transition.
  • For FRS_ERR_INVALID_SERVICE_PARAMETER, record invalid_service_parameter_first_status for the earliest lower-level diagnostic.

For support escalation involving FRS_ERR_INVALID_SERVICE_PARAMETER, retain decimal 8017, hexadecimal 0x00001F51, the API, UTC time, target identity, and first subsystem-specific status. For FRS_ERR_INVALID_SERVICE_PARAMETER, include the smallest reproducible request and evidence that distinguishes this condition from nearby codes. In the context of FRS_ERR_INVALID_SERVICE_PARAMETER, frs is legacy technology. for sysvol, determine the domain’s actual migration state before applying an frs recovery procedure, because a domain already migrated to dfs replication has a different owner and recovery model.

Difference from nearby results

For FRS_ERR_INVALID_SERVICE_PARAMETER, FRS_ERR_INVALID_API_SEQUENCE concerns call ordering rather than the value of an individual parameter

Practical validation scenario

A tool sends a member GUID copied from another replica set. Re-enumerating the target set and using its current GUID resolves the request. The negative test should preserve the responsible condition and reproduce FRS_ERR_INVALID_SERVICE_PARAMETER; the recovery test should change only the identified cause, repeat the same operation, and verify both success and the absence of an unintended partial side effect.

Developer and administrator guidance

Administrators handling FRS_ERR_INVALID_SERVICE_PARAMETER must identify whether SYSVOL is actually owned by FRS or by DFS Replication before recovery. For FRS_ERR_INVALID_SERVICE_PARAMETER, developers and scripts should record directional partners, replica-set identity, and the first FRS event rather than treating a successful HTTP, RPC, or service-control call as proof that replication completed. Code that exposes FRS_ERR_INVALID_SERVICE_PARAMETER through RPC, JSON, REST, PowerShell, or another protocol should preserve the Win32 domain, decimal 8017, hexadecimal 0x00001F51, and original component diagnostic.
