Fix FWP_E_PROVIDER_CONTEXT_NOT_FOUND 0X80320006

You're in the middle of connecting to your corporate VPN, or maybe you just rebooted after a Windows Update, and boom — you get hit with error 0X80320006, FWP_E_PROVIDER_CONTEXT_NOT_FOUND. It usually pops up in event logs under Microsoft-Windows-Windows Firewall With Advanced Security/Operational, or right in a third-party VPN client that's trying to register a filter. I've seen this most often after a firewall driver update (like from McAfee, Norton, or even Windows Defender's own filter) or after a VPN client upgrade that didn't clean up its old providers.

Root Cause in Plain English

Windows Filtering Platform (WFP) is the backbone of all network filtering in Windows — VPNs, firewalls, even the built-in Defender firewall all register something called a provider context with the WFP engine. Think of it like a permission slip or a set of rules that says "this network traffic is allowed through this tunnel." When a program creates a filter (like a VPN client), it also tells WFP about its provider and the context for that filter.

The problem: the filter still exists in WFP, but the provider context it points to was either deleted by an uninstall, corrupted during an update, or never properly created. The WFP engine says "I have a filter that references context ABC, but I can't find context ABC anywhere in my database." That's the 0X80320006 error.

How to Fix It

We're going to do this in a specific order. Don't skip steps.

Step 1: Identify the Offending Program

Most of the time, this is tied to a specific software. Think back — did you just update a VPN (like Cisco AnyConnect, Pulse Secure, OpenVPN, or a corporate VPN)? Or did you install/update a firewall that isn't Windows Defender? If you're not sure, check Add/Remove Programs for anything with "VPN" or "firewall" in the name.

What you'll see after this step: nothing happens yet, but you'll know which software to target.

Step 2: Repair the Offending Software

Don't immediately uninstall. Many VPN clients and firewall suites have a repair option.

Go to Settings > Apps > Installed apps (Windows 10) or Apps & features (Windows 11).
Find the program you suspect (e.g., Cisco AnyConnect, Symantec Endpoint Protection).
Click the three dots next to it and choose Modify or Change.
Look for a Repair or Reinstall option — it's often a checkbox or a button in the installer wizard.
Run through the repair wizard. It will re-register its WFP provider contexts.

After this step: reboot, then test if the error returns. If it's gone, you're done. If not, move to step 3.

Step 3: Uninstall and Reinstall the Software

A repair sometimes doesn't get rid of stale WFP contexts. A clean uninstall might remove the orphaned filter, and a fresh install will create new contexts.

Uninstall the program normally through Settings > Apps.
Reboot — this is critical. Some uninstallers don't fully clean up WFP until a reboot.
After reboot, open a command prompt as admin and run:
```
netsh wfp show filters
```
This will list all WFP filters. Look for any filter whose name or description still references the uninstalled software. If you see a filter that references a provider context you know is gone, that's the culprit.
If you find it, note the filter ID. Then remove it with:
```
netsh wfp delete filter id=<filterID>
```
Replace <filterID> with the actual ID (just the number).
Now reinstall the software fresh.

After this step: reboot again and test. If the error is gone, you're good. If it still appears, we go nuclear.

Step 4: Reset the Windows Filtering Platform (Nuclear Option)

This will wipe all WFP filters and provider contexts back to a clean Windows state. It will break any third-party firewall or VPN until you reinstall them.

Open an elevated command prompt (Run as Administrator).
Run this command:
```
netsh wfp reset
```
You'll see a message like "Resetting WFP configuration... OK."
Reboot.
After reboot, your Windows Defender Firewall will be back to default. You'll need to reinstall any third-party firewall or VPN that was using WFP.

After this step: test your network. The error should be gone. If not, something else is going on.

What to Check If It Still Fails

If you've done all of the above and the error still shows up, you're probably dealing with one of two things:

Corrupt system files: Run sfc /scannow from an admin command prompt. If it finds integrity violations, run DISM /Online /Cleanup-Image /RestoreHealth next.
A driver conflict: Check for any network adapter filter drivers. Open Device Manager, go to View > Show hidden devices, expand Network adapters, and look for anything labeled "WFP Lightweight Filter" or "Virtual Network Adapter" from an old VPN. Uninstall those, reboot, and try again.

I've seen this error about a dozen times in the last three years. Nine times out of ten, it's a botched Cisco AnyConnect update that leaves dead provider contexts behind. Steps 2 and 3 catch most cases. Only hit step 4 if you're out of options.
