Always On VPN at Workplace Ninja Summit 2022

The Workplace Ninja Summit takes place from 12-14 September 2022 in Lucerne, Switzerland. The conference focuses on endpoint management and security with platforms such as System Center Configuration Manager (SCCM) and Microsoft Endpoint Manager/Intune.

Conference Sessions

If you are participating in the conference, be sure to attend one of my sessions! I’m delivering the following three talks during the event.

Windows Always On VPN and Autopilot: Better Together

In this talk, I’ll cover in detail the critical aspects of implementing Always On VPN to support Autopilot provision with Intune.

Deploying On-premises Certificates with Intune

This session will explore the options for deploying enterprise PKI certificates using Intune. I’ll be sharing lots of security and implementation best practices.

Deploying Always On VPN with Intune: The Good, The Bad, and the Ugly

This talk will dive into the options for deploying Always On VPN using Intune. I’ll be covering many tips, tricks, and best practices and shining a light on many limitations and shortcomings of using Intune for Always On VPN.

Join Me!

Unfortunately, the conference is sold out, so if you haven’t made arrangements to attend you’ll have to wait until next year. If you are attending, please be sure to say hello!

Always On VPN NPS Auditing and Logging

The Network Policy Server (NPS) event log is incredibly valuable for administrators when troubleshooting Always On VPN user tunnel connectivity issues. Administrators can find these pertinent events by opening the Event Viewer on the NPS server (eventvwr.msc) and navigating to Custom View > Server Roles > Network Policy and Access Services.

Event Logs

When configured correctly, event logs will record the disposition of all authentication requests, allowed or denied. The two most common recorded events are event IDs 6272 (access granted) and 6273 (access denied).

NPS Event ID 6272 – Access granted.

NPS Event ID 6273 – Access denied.

Auditing

In some cases, administrators may find none of these events recorded even though user authentication is working correctly. Here, the only events recorded are NPS informational events indicating which domain controller the NPS server is using to perform authentication.

The lack of 6272 and 6273 events in the event log indicates that auditing for NPS events is not enabled. Open an elevated PowerShell window and run the following command to view the current auditing setting for NPS events.

auditpol.exe /get /subcategory:”Network Policy Server”

Open an elevated PowerShell window and run the following command to enable auditing for NPS events.

auditpol.exe /set /subcategory:”Network Policy Server” /success:enable /failure:enable

Group Policy

Alternatively, consider using Active Directory group policy to enforce the NPS server auditing settings. Open the Group Policy Management Console (GPMC) and create a new GPO. Next, navigate to Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Audit Policy > Audit account logon events and select the option to audit both success and failure attempts.

Once complete, link this GPO to the OU where the NPS servers reside.

Missing Events

If auditing is enabled and there are no recorded 6272 or 6273 events, the NPS server did not receive any authentication requests from the VPN server. Review the event logs on any other NPS servers if there is more than one configured. In addition, this may indicate that network communication between the VPN and NPS server is blocked. Ensure network connectivity and name resolution are working as expected.

Endpoint Manager and Intune Learning Resources for Always On VPN Administrators

Microsoft Endpoint Manager (MEM), formerly Intune, is the recommended solution for deploying and managing Windows Always On VPN client configuration settings. Always On VPN is designed for Mobile Device Management (MDM), with configuration settings deployed specifically to the VPNv2 Configuration Service Provider (CSP) interface.

Resources

Getting up to speed on all things MEM isn’t difficult at all. I’ve found the MEM community to be exceedingly helpful, and there are many available training resources in various formats from which to choose.

Books

The following is a list of Microsoft Endpoint Manager books Always On VPN administrators will find most helpful for learning about MEM.

YouTube

The Intune Training channel on YouTube is an incredibly valuable resource for Always On VPN administrators learning MEM. Hosted by Steven Hosking, Adam Gross, and Ben Reader, there are countless videos covering important MEM configuration tasks.

Pluralsight

Pluralsight offers video training courses for a wide variety of IT-related topics. Recently I published the  Implementing Always On VPN video training course. There are several Microsoft Endpoint Manager video training courses available as well. Pluralsight is available via subscription. You can sign up for a free trial here if you don’t have a subscription.

Conferences

The Midwest Management Summit (MMS) is the premier event for systems management professionals. Their annual conference takes place each spring in the U.S. (Minneapolis, MN). The event is the best place to learn about Microsoft Endpoint Manager and network with systems management professionals worldwide.

Additional Resources

As a reminder, MEM topics such as certificate deployment and Always On VPN profile deployment and management are covered in detail in both my Implementing Always On VPN book and the Implementing Always On VPN video training course on Pluralsight. 😁
