Microsoft Releases Out-Of-Band Windows Server 2019 Update To Address Hyper-V, ReFS and VPN Issues

Microsoft has started rolling out an out-of-band update for Windows Server 2019. The same KB5010791 patch addresses a couple of critical issues introduced with January 2021 Patch Tuesday updates.

According to the release notes, this update fixes an issue that causes unexpected restarts on Windows Server domain controllers. Microsoft has also addressed a bug that caused ReFS (Resilient File System) formatted hard drives not to show up at all or to show up as raw, unformatted disks. This update also includes certain improvements to fix broken VPN connections on Windows Server machines. You can check out the full list of improvements in the changelog below:

  • Addresses a known issue that might cause IP Security (IPSEC) connections that contain a Vendor ID to fail. VPN connections using Layer 2 Tunneling Protocol (L2TP) or IP security Internet Key Exchange (IPSEC IKE) might also be affected.
  • Addresses a known issue that might cause Windows Servers to restart unexpectedly after installing the January 11, 2022 update on domain controllers (DCs).
  • Addresses an issue that prevents Active Directory (AD) attributes from being written properly during a Lightweight Directory Access Protocol (LDAP) modify operation when you make multiple attribute changes.
  • Addresses an issue that might prevent removable media that is formatted using the Resilient File System (ReFS) from mounting or might cause the removable media to mount in the RAW file format. This issue occurs after installing the January 11, 2022 Windows update.

Microsoft releases out-of-band update for Windows Server versions 2022, 20H2, 20H1, 2016, 2012 R2

The out-of-band update follows the release of emergency patches for Windows Server versions 2022, 20H2, 20H1, 2016, 2012 R2. These Windows Server updates released on January 17 addressed all the aforementioned issues. Microsoft also rolled out updates for Windows 11, Windows 10, Windows 8, and Windows 7 to resolve the L2TP VPN connectivity problems.

Keep in mind that the KB5010791 update is available via Windows Update, and it can also be installed via standalone packages available on the Microsoft Update Catalog.
