What does HRESULT 0x80090301 (SEC_E_INVALID_HANDLE) mean?

SEC_E_INVALID_HANDLE

Meaning of SEC_E_INVALID_HANDLE

SEC_E_INVALID_HANDLE (0x80090301) means a security handle supplied to an SSPI operation is invalid. The handle may represent credentials or a security context; the code is not specific to CredSSP or to one authentication protocol.

Diagnostic checks

• Identify the exact SSPI function and whether the failing input is a credential handle, context handle, or another security object.
• Trace acquisition or context creation through the failing call and record any earlier free, delete, reset, or replacement operation.
• Check concurrent access and object ownership when one thread can tear down a handle while another thread still uses it.

Recovery

Recreate the invalid security object through the correct SSPI lifecycle and prevent stale-handle reuse. If recreating the handle only masks the problem temporarily, instrument the handle's creation and destruction rather than changing authentication policy or credentials without evidence.
