How to fix error error-ipsec-mm-auth-pending-deletion in Windows 11

Solution Steps

1. 1 Press Windows key + R, type "secpol.msc" and press Enter. This opens the Local Security Policy editor.
2. 2 Navigate to "IPsec Policies on Local Computer".
3. 3 Right-click on the policy that is causing the error and select "Properties".
4. 4 Go to the "Security Rules" tab. Look for any rules that might reference the authentication method that is pending deletion.
5. 5 For each rule that uses the method, either edit the rule to use a different authentication method, or remove the rule entirely. To edit, select the rule and click "Edit", then change the authentication method.
6. 6 After removing all references, the pending deletion should be cleared. If the method is still listed, you can try to delete it again.
7. 7 Click OK and run "gpupdate /force" in an admin command prompt.
