Microsoft recently confirmed a problem with Direct Access on Windows 10 and Windows 11 devices in some of its recent updates.
The problem affects devices running Windows 11 versions 21H2 and 22H2, or all release versions of Windows 11 and Windows 10 versions 20H2, 21H1, 21H2, and 22H2, as well as Enterprise versions LTSC 2019, Windows Server 2022, and Windows Server 2019.
The problem manifests itself after installing the October preview updates or newer updates on affected systems, as well as after a short-term loss of network connection or switching between Wi-Fi networks or access points. However, other remote access solutions such as VPN (Remote Access Server) and Always On VPN (AOVPN) are not yet affected.
To fix the issue, Microsoft first issued a Known Issue rollback for Windows 10 and 11 devices. However, it could take up to 24 hours for the update to reach non-managed business machines. Meanwhile, Microsoft advises IT administrators to download and install a special group policy to fix DirectAccess remote connectivity issues on enterprise Windows devices.
It then imposed a compatibility freeze on affected devices to prevent them from installing version 22H2 and recommends users who have already upgraded their apps and games to the latest available version while the company works on a fix.
