Installing the LAN over USB Windows device driver

When you install a Windows operating system, there might be an unknown RNDIS device in the Device Manager. Lenovo provides a Windows INF file that identifies this device.

Complete the following steps to install ibm_rndis_server_os.inf:
You only have to perform these steps if the compute node is running a Windows operating system and the ibm_rndis_server_os.inf file has not been previously installed. The file only has to be installed once. It is required by Windows operating systems to detect and use the LAN over USB functionality.

  1. Click Administrative Tools > Computer Management > Device Manager and find the RNDIS Device. Click Properties > Driver > Reinstall driver. Point the solution to the \Windows\inf directory where it can find the ibm_rndis_server_os.inf file and install the device.

  2. Click Administrative Tools > Device Manager. Right-click Network adapters and select Scan for hardware changes. A small pop-up confirms that the Ethernet device is found and installed. The New Hardware Wizard starts automatically.
  3. When you are prompted Can Windows connect to Windows Update to search for software?, select No, not this time. Click Next to continue.
  4. When you are prompted What do you want the wizard to do?, select Install from a list or specific location (Advanced). Click Next to continue.
  5. When you are prompted Please choose your search and installation options, select Don't search. I will choose the driver to install. Click Next to continue.
  6. When you are prompted Select a hardware type, and then click Next, select Network adapters. Click Next to continue.
  7. When you are prompted with the statement Completing the Found New Hardware Wizard, click Finish. A new local area connection appears. If the message This connection has limited or no connectivity is displayed, ignore this message.
  8. Return to the Device Manager. Lenovo USB Remote NDIS Network Device appears under Network Adapters.
  9. Use the Lenovo XClarity Controller interface to view or set the IP address for the LAN adapter.
