Microsoft recently issued an out-of-band update for a problem that prevents some printers, scanners, and multifunction devices from working. Now, the company has outlined steps to temporarily mitigate the issue.
The complication only affects a small set of devices, but for anyone with a device that runs into it, updates and mitigation steps are always welcome. Microsoft explains which devices are affected in a support doc (opens in new tab):
Here are the steps for temporary mitigation from Microsoft (opens in new tab):
To use the temporary mitigation in your environment, follow these steps on all your domain controllers:
- On your Domain Controllers, set the temporary mitigation registry value listed below to 1 (enable) by using the Registry Editor or the automation tools available in your environment.Note: This step can be done before or after steps 2 and 3.
- Install an update that allows the temporary mitigation available in updates released July 27, 2021 or later (below are the first updates to allow the temporary mitigation):
- Windows Server 2019: KB5005394 (opens in new tab)
- Windows Server 2016: KB5005393 (opens in new tab)
- Windows Server 2012 R2: KB5005391 (opens in new tab)
- Windows Server 2012: KB5005389 (opens in new tab)
- Windows Server 2008 R2 SP1: KB5005392 (opens in new tab)
- Windows Server 2008 SP2: KB5005390 (opens in new tab)
- Restart your domain controller.
Note that editing the registry incorrectly can cause serious issues. Here is the registry value that Microsoft mentions in its instructions:
|Device Manager Name||Version and Update|
|Data||1 – Enable temporary mitigation.|
0 – Enable default behavior, requiring your devices into compliance with section 3.2.1 of RFC 4556 spec.
