DirectAccess Fails on Windows 11 24H2

Microsoft recently released Windows 11 24H2. Not long after the release there have been numerous reports of DirectAccess failing after performing an in-place upgrade from previous versions of Windows 11. New installations of Windows 11 24H2 experience the same problem.

Update 10/28/2024: This issue is resolved with KB5044384.

Testing

After downloading and configuring a Windows 11 24H2 test client I was able to quickly reproduce the issue. While previous versions of Windows 11 can connect to my test DirectAccess server without issue, the Windows 11 24H2 client fails.

Troubleshooting

Looking at the DirectAccess status indicator in the UI the DirectAccess connection remains ‘Connecting’ perpetually. Further investigation indicates an IP-HTTPS interface error. Running the command netsh.exe interface httpstunnel show interface reveals an error code 0x57 (invalid parameter) with the following error message.

Failed to connect to the IPHTTPS server. Waiting to reconnect.

Workaround

Currently there is no known root cause for this issue and there is no available workaround. Administrators should delay upgrading to Windows 11 24H2 if DirectAccess is deployed in the organization. I will continue to investigate and post additional information as I learn more. Stay tuned!

Microsoft DirectAccess Now Formally Deprecated

Microsoft DirectAccess Formally Deprecated

Today, Microsoft has announced the formal deprecation of DirectAccess. Microsoft DirectAccess is a widely deployed enterprise secure remote access solution that provides seamless, transparent, always-on remote network connectivity for managed (domain-joined) Windows clients. First introduced in Windows Server 2008 R2, it’s been a popular solution with many advantages over ordinary VPN technologies of the past.

Windows Server 2012

DirectAccess was almost entirely rewritten in Windows Server 2012. Many of the features and enhancements offered for DirectAccess with the Unified Access Gateway (UAG – a separate product with additional costs) were built into the operating system directly. In addition, Microsoft introduced integrated load balancing and geographic redundancy features.

Demise of DirectAccess

DirectAccess relies heavily on classic on-premises technologies like Active Directory. All DirectAccess servers and clients must be joined to a domain. In addition, all DirectAccess clients must be running the Enterprise edition of Windows. With organizations rapidly adopting cloud services such as Azure and Entra ID, Microsoft began to develop an alternative solution that better integrated with the cloud. That solution is Always On VPN. With that, Microsoft stopped developing DirectAccess after the release of Windows Server 2012 R2. No new features or capabilities have been added to DirectAccess since that time.

Deprecation

We’ve been speculating about the end of life for DirectAccess for quite some time now. However, this formal deprecation announcement from Microsoft is official. It is the end of the road for this technology. To be clear, though, DirectAccess is available today in Windows Server 2022 and Windows 11. DirectAccess will be included in the upcoming release of Windows Server 2025. However, formal deprecation from Microsoft means they will remove DirectAccess components from the next release of the operating system.

What Happens Now?

Organizations should begin formal planning efforts to migrate away from DirectAccess. Here are a few popular solutions to consider.

Always On VPN

Always On VPN is the direct replacement for DirectAccess. It was designed to provide feature parity for DirectAccess, with seamless, transparent, always-on remote network connectivity. However, Always On VPN better integrates with Entra ID and supports conditional access. It does not require domain-joined devices or servers and works well with cloud-native endpoints. Always On VPN is a good choice for organizations that employ hybrid Entra-joined devices.

Entra Private Access

Entra Private Access, part of the Entra Global Secure Access suite, is an identity-centric zero-trust network access (ZTNA) solution from Microsoft. It is in public preview now and has some compelling advantages over traditional VPNs. However, Entra Private Access is not feature complete today. In addition, it is best suited to cloud-native (Entra-joined only) endpoints.

Absolute Secure Access

Absolute Secure Access (formerly NetMotion Mobility) is a premium enterprise remote access solution with many advanced options. It is by far the best solution on the market today. Absolute Secure Access is a software solution that supports zero-trust configuration and includes many features to improve and enhance security, performance, and visibility. In addition, it provides cross-platform support, including Windows, macOS, iOS, and Android operating systems.
