How to Troubleshoot a Yellow Exclamation Mark in Device Manager over the Intel® Smart Network Interface Card (NIC)


Intel® Gigabit CT Desktop Adapter Onboard NIC

Windows Server 2016*, Windows® 10, 64-bit*


Steps to follow when Device Manager reports an error involving the network connection

Device Manager would show: This device cannot start _ code : 10


Proceed as follows, depending on the NIC set-up:

  1. For built-in NICs: If it is not going to be used, disable it from within the mainboard BIOS; check with the board manufacturer if in doubt on how to do this. 
  2. In the case of an external, Peripheral Component Interconnect Express (PCIe*), such as an Intel® Gigabit CT Desktop Adapter: If the Windows* Device Manager conflict follows it; we comment that while Windows® 10 is among the supported Operating Systems (OSs) for this NIC, the driver availability for it is generic (in-box; click here for more information); then proceed as follows:
    1. Search for the updated driver via Device Manager; see steps 4 through 6 of our How to Manually Install Intel® Network Adapter Drivers in Windows* article.  
    2. Identify and find drivers by going to Intel Download Center and clicking on Ethernet and apply a filter based on your Operating System.
    3. Run a Windows update and see if this suggests a new driver update.

In the case of Windows* Server 2016 and later, especially when using the onboard NIC ports, try the latest Intel® Ethernet Adapter Complete Driver Pack by executing its Autorun as follows:

  1. Remove the network cable.
  2. From Device Manager, uninstall all of the entries found under Network Adapters.
  3. Restart the system. Note: Once back into the Operating System, this would recognize the onboard NIC as Other Devices.
  4. Proceed to install the executable for the driver.  Wait until it confirms its successful installation.
  5. Plug the network cable
