Microsoft Acknowledges KB5036909 Issues in Windows Server Affecting NTLM Traffic and LSASS

Deluxe company -

Microsoft has acknowledged additional complications in KB5036909 for Windows Server 2022 that might potentially result in a sharp increase in NTLM traffic and initiate LSASS crashes, subsequently leading to automatic system rebooting. For rectification of problems associated with KB5036909, it is feasible to execute DISM /online /get-packages and manually eliminate the package.

The security updates for Windows implemented in April 2024 have been contentious for all users, encompassing both individuals and corporations. Three severe glitches in the April 2024 Patch have been identified and reported by Windows Latest, with the fourth fresh malfunction identified in Windows Server 2022.

Via an update to its support document, Microsoft cautioned about the issues affiliated with Windows Server 2022. As per Microsoft, administrators are likely to experience a sudden surge in NTLM authentication traffic. For those unfamiliar, NTLM serves as an authentication protocol that confirms user identity in order to establish a connection.

Although NTLM is a legacy protocol not as widely utilized as Kerberos, it was adversely affected by the security update in April. Microsoft also notified that service crash issues could be encountered by Windows Server computers operating as a Domain Controller, apart from the surge in NTLM traffic.

The sudden failure of the Local Security Authority Subsystem Service (LSASS) can cause your computer to restart. This issue is prevalent in Windows Server 2022, extending to all previous versions including Windows Server 2008.

The following is a comprehensive list of impacted Windows versions:

To rectify this, we must wait for Microsoft to release a correction. As is customary, you can opt to remove the update using PowerShell.

Here are the steps to remove the April 2024 update from Windows Server 2022 using DISM:

You are able to replicate the same process for other versions of Windows, just remember to swap out the KB ID. It’s advisable to put the updates on hold until the patches are ready.

Something to keep in mind is that the April 2024 update also introduced a couple of other problems for Windows Server.

There’s a chance you might run into an error when attempting to alter the profile picture on your Windows Server computer. Often, the chosen image becomes the new profile image and subsequently, the 0x80070520 error shows up.

This error wrongly suggests that the profile photo was not able to be saved.

On consumer editions of Windows 11, a problem has been identified in connection with a local account, as verified through our independent testing mentioned in a different post.

The difficulties include a potential failure of VPN software to establish a connection, which poses challenges to using your PC securely. It’s been almost a month since the update was launched, and these issues are still not adequately addressed.

A couple of weeks ago, Microsoft inadvertently incorporated the Copilot app into Windows Server computers through an Edge browser update. Contrarily, the Copilot app is not provided for Windows Server in consumer editions.

Nevertheless, Microsoft acknowledged the issue and rectified the error by releasing a new update for the Edge that removed the app.
