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

Yellow Exclamation Mark in Device Manager for the Intel® Smart Network Interface Card (NIC)

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.
