All methods MUST NOT throw exceptions.

The server SHOULD<4> enforce security measures to verify that the caller has the required permissions to execute any method. If the server enforces security measures, and the caller does not have the required credentials, then the server MUST fail the call and return E_ACCESSDENIED. For more details on how to determine the identity of the caller for the purpose of performing an access check, see [MS-RPCE] section 3.3.3.1.3.

For all methods, unless otherwise specified, if any of the parameters is NULL, the server MUST fail the call with E_INVALIDARG.

For all methods, when the server returns ZERO to the client, the server MUST persist all state information into an implementation-specific configuration store.
