Windows 7: Network Controller error in Device Manager

Network Controller error in Device Manager

I have a Dell XPS 8700 machine at our office in which something went haywire with the HDD, so I installed a brand new HDD and did a fresh install of Windows. After everything completed and all updates were installed, I still had 3 devices with yellow triangles listed under Unknown Devices in Device Manager.

I went to the Dell website and put in the machine's service code, and found several drivers that I installed, which fixed 2 of the Unknown Devices. However one still remains, called Network Controller.

This particular machine had its ethernet port on the motherboard wiped out during a lightning storm early last year, which affected a number of devices in the office, anything from PC's to printers, even to the HVAC systems. I discovered the dead ethernet port on the machine, so I ordered and installed an Intel EXPI9301STBLK gigabit PCI-e discreet network adapter.

Everything seems to be working fine on the machine, other than "Network Controller" being listed as an unknown device in Device Manager. In Network and Sharing Center, the only items listed as adapters are the Bluetooth connection and the Intel discreet network adapter. Those items are also listed in Device Manager under Network Adapters as all functioning properly.

I have looked in the device property details for the "Network Controller" and cannot find any information in any of the entries about what manufacturer or model the device is, so I really don't know where to look for a driver.

Any ideas?

And in case this helps, I tried "wmic baseboard" at a command prompt - the board manuf. is of course Dell, product 0KWVT8, serial CN7220036E019Z.

Well I downloaded every Network driver available from the Dell website for my particular service code, and finally that got rid of the Network Controller error in Device Manager.

However I still had a yellow triangle showing on the computer system in Devices and Printers. If I right-click and troubleshoot, it tells me there's a problem with the "Bluetooth Server". I went into the Bluetooth Adapter properties and disabled the adapter (don't need Bluetooth) and that seems to have cleared out the yellow triangle.

However still doesn't answer why that was happening. No matter I guess, seems okay now.
