NWCONFIG-X-480: Warning: An attempt to open configuration files IOAUTO.NCF and MSAUTO.NCF failed. Error code: code
You may still configure drivers, but later you will have to manually add the LOAD commands to the configuration file if you want the driver LOAD operations to remain after the server reboots.
Source: NWCONFIG.NLM
Action: See Resolving File I/O Errors in the Traditional File Services Administration Guide. You can also do as the message states and manually edit the IOAUTO.NCF and MSAUTO.NCF files by loading NWCONFIG and selecting Maintenance/Selective Install.
