1. 1 First, verify that your user account is allowed to connect to the VPN. Contact your network administrator to confirm that your account has the necessary permissions.
2. 2 If you're using certificate-based authentication, ensure your certificate is valid and trusted. Press Windows key + R, type 'certmgr.msc', and press Enter. Look under 'Personal' → 'Certificates' for your certificate. Check its expiration date and trust chain.
3. 3 If the certificate is expired or untrusted, you'll need to obtain a new one from your organization.
4. 4 Check the VPN connection properties. Press Windows key + R, type 'ncpa.cpl', and press Enter. Right-click your VPN connection and select 'Properties'.
5. 5 Go to the 'Security' tab and ensure the authentication method is set correctly. If using certificates, select 'Use smart card' or 'Use certificate' as appropriate.
6. 6 If your VPN uses a pre-shared key, verify that the key is correct and that the server allows your IP address.
7. 7 Try using a different VPN protocol, such as IKEv2, which may have different authorization requirements.
8. 8 Finally, check the Windows Event Viewer for more details. Press Win+X and select 'Event Viewer'. Go to 'Windows Logs' → 'Security' and look for audit failures around the time of the error. This can give you more insight.
