Fix 0XC0230006 NDIS Adapter Not Found – 3 Steps

When Windows can't see your network adapter, you'll hit this error in apps like Hyper-V or VPN clients. Here's how to fix it fast, from a simple reboot to a full driver reset.

What is 0XC0230006?

This error means Windows can't find your network interface or it isn't ready. It shows up when you try to start a VPN client, a Hyper-V virtual switch, or any app that talks directly to the NDIS (Network Driver Interface Specification) stack. I've seen it happen after a Windows update, a driver hiccup, or even just a flaky USB Wi-Fi adapter.

If you're in a hurry, start with Fix 1. Most people won't need to go past Fix 2. But if you're still stuck, Fix 3 is the nuclear option—and it works.

Fix 1: Quick Reboot (30 seconds)

I know it sounds too simple, but this error often fires because the network adapter is in a weird state after waking from sleep or after a driver update. A full shutdown clears that state.

Save your work.
Click Start > Power > Shut down (not restart—shut down completely).
Wait 10 seconds, then power back on.

If the error's gone, you're done. If not, move on—the reboot didn't reset the driver stack properly, which is more common than you'd think.

Fix 2: Disable and Re-enable the Adapter (5 minutes)

This forces Windows to reinitialize the NDIS driver. It's the fix I recommend most often for this specific error.

Press Win + X and select Device Manager.
Expand Network adapters.
Right-click your active adapter (e.g., Intel Wi-Fi 6 AX200 or Realtek PCIe GbE) and select Disable device.
Wait 10 seconds, then right-click it again and select Enable device.

That's it. The adapter gets a fresh start, and the NDIS binding should come back. If the error persists, try this variation:

In Device Manager, click View > Show hidden devices.
Look for greyed-out ghost adapters—old virtual ones from Hyper-V or VPNs. Right-click and Uninstall device for any that aren't active.
Then restart your PC.

Ghost adapters cause more conflicts than people realize. I've seen three virtual adapters silently collide with the real one.

Fix 3: Reset the Network Stack (15+ minutes)

If the error still shows up, something deeper is broken—likely corrupted Winsock or TCP/IP settings. This resets the whole network stack, so it's a bit of a hammer. But it works.

Open Command Prompt as administrator. Press Win + X and choose Terminal (Admin) or Command Prompt (Admin).
Run these commands one at a time, pressing Enter after each:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart your computer.

This clears any corrupt LSP (Layered Service Provider) entries that might block NDIS from seeing the adapter. I've fixed this exact error twice with just the winsock reset.

If you're still stuck, a driver reinstall is your last move:

In Device Manager, right-click your adapter and select Uninstall device. Check Delete the driver software for this device if you see it.
Restart. Windows will auto-install the correct driver.

If that doesn't work, go to your adapter manufacturer's site (Intel, Realtek, etc.) and grab the latest driver manually. Skip the generic Microsoft driver—it's often the culprit.

When to blame your router or NIC

Sometimes the adapter itself is fine, but the network cable or Wi-Fi signal is flaky. That won't cause this error directly, but a dying NIC can trigger it during high traffic. If you've done all the fixes and it still happens randomly, try another adapter or a USB Wi-Fi dongle for a day. I've had a laptop's internal card fail exactly this way.

You've got this. Start with the reboot, then work your way down. Most people fix it at Fix 2.
