Windows Server 2008 - ethernet drivers

Had to rebuild a failed Windows Server 2008 system - replaced drive.

Fresh install of the OS but can’t seem to get the ethernet driver installed so the machine can get back online?

NIC is active - activity lights. But the OS doesn’t have a driver and I’ve searched for a solution.

Any help? Truly appreciate it.

Application I’m running needs the ancient OS.

Could you provide more information? What is the vendor of the NIC? Model? etc?
