+ * @brief Adds server address information in the local endpoint map.
+ *
+ * @param[in]  iface    The interface specification to register with the local
+ *                      endpoint map.
+ *
+ * @param[in]  binding  The server binding handles over which the server can
+ *                      receive remote procedure calls.
+ *
+ * @param[in]  object_guid The object GUID that the server offers. The server
+ *                         application constructs this vector.
+ *
+ * @param[in]  annotation  Defines a character string comment applied to the
+ *                         element added to the local endpoint map. The string
+ *                         can be up to 64 characters long, including the null
+ *                         terminating character. Strings longer than 64
+ *                         characters are truncated. The application supplies
+ *                         the value NULL or the string "" to indicate an empty
+ *                         annotation string.
+ *
+ *                         When replacing elements, the annotation string
+ *                         supplied, including an empty annotation string,
+ *                         replaces any existing annotation string.
+ *
+ * @return                 An NTSTATUS error code.
