LAN Driver Issues on Windows Server 2019 & 2022 – Lenovo M70s

I’m currently running Windows Server 2022 on one device and Windows Server 2019 on another both Lenovo M70s models. Unfortunately, I’m encountering the same issue on both: the systems are unable to detect LAN drivers.

I’ve manually attempted to install various drivers from the Lenovo Support site, but none have worked so far. I’m beginning to wonder if Windows Server might not be fully compatible with the hardware on these devices.

Here are the details of the two machines:

PC 1

  • Model: Lenovo M70s

Serial Number: PC10HLLB

PC 2

Model: Lenovo M70s Serial Number: PC11EFMK

Any guidance or suggestions would be greatly appreciated!

    Thanks you for the guide, I have inserted a screenshot of the hardware IDs for the win server 2022 (PC) When clicking on the driver pack link it shows me a "Release_30.3.zip" which have downloaded and tried by Device Manager → Right-click on network device → Update driver → Browse manually → Point to the extracted folder. I got an error "Windows was unable to install your Ethernet Controller" https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html.

    I carried out the other steps too but still no joy.

    Based on your description and my knowledge, you're running Windows Server 2022 and 2019 on Lenovo M70s models, but both systems are not detecting LAN drivers—even after trying Lenovo’s official drivers. This is a common issue when using desktop-class hardware with server-class operating systems, which sometimes lack built-in driver support for consumer hardware.

    So I have som step-by-step solutions for you to try it out and let me know the result :

    1. Identify the LAN Chipset

    On both machines, run the following from Command Prompt or PowerShell:

    wmic nic get Name, PNPDeviceID

    Or check Device Manager:

    • Look for the "Network Controller" with an exclamation mark under “Other devices”.
    • Right-click → Properties → Details tab → drop down to Hardware Ids.

    You should see something like:

    PCI\VEN_8086&DEV_15F3...

    This tells you the vendor (VEN_8086 = Intel) and device ID (e.g., DEV_15F3).

    Send me those values if you’re unsure, and I’ll look up the correct driver.

    1. Download the Raw Intel/Realtek Drivers

    Lenovo’s site often bundles drivers with OS checks. Instead:

    This method bypasses the OS check and allows manual installation.

    1. Disable Driver Signature Enforcement (if needed)

    If Windows Server blocks unsigned drivers:

    • Reboot → Press F8 (if supported) or boot into Advanced Startup.
    • Choose Disable driver signature enforcement.
    • Then install the driver manually.
    1. Use Windows 10 Drivers

    In many cases, Windows 10 drivers work fine for Server 2019/2022.

    • On the Lenovo support page for M70s, choose Windows 10 64-bit and try downloading:
      • Intel LAN Driver for Windows 10: e.g., Intel LAN Driver v12.x.x.x
      • Or Realtek, if that's the onboard NIC.

    Use the .INF method from Device Manager for manual installation.
