3.1.4.3.6.1 CLUSCTL_NETINTERFACE_UNKNOWN
The CLUSCTL_NETINTERFACE_UNKNOWN cluster network interface control code verifies that control codes are being processed on the node where execution of the control is directed.
The server SHOULD accept a CLUSCTL_NETINTERFACE_UNKNOWN cluster network interface control code request if its protocol server state is read-only, and the server MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.
Upon successful completion of the method, the server MUST return 0x00000000 (ERROR_SUCCESS). If control codes are not being processed, the server is required to return an implementation-specific error code.
