Microsoft has just confirmed a new issue introduced by the June 11 cumulative updates for a series of Windows 10 versions.
The software giant says that installing these cumulative updates could cause devices using PXE from a WDS or SCCM server to fail to start.
However, please note that this issue does not affect consumer editions of Windows 10, but only server SKUs, as you can find in the table below. Microsoft explains the following:
“Devices that start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM) may fail to start with the error "Status: 0xc0000001, Info: A required device isn't connected or can't be accessed" after installing [June 11 cumulative updates] on a WDS server.”
Workaround already available
The affected Windows 10 versions are the ones listed below:
Windows Server 2008 SP2 |
Windows Server 2008 R2 SP1 |
Windows Server 2012 |
Windows Server 2012 R2 |
Windows Server 2016 |
Windows Server, version 1803 |
Windows Server 2019 |
Windows Server, version 1809 |
Windows Server, version 1903 |
“Try the default values for TFTP block size and TFTP window size first but depending on your environment and overall settings, you may need to adjust them for your setup. You can also try the Enable a PXE responder without Windows Deployment Service setting,” Microsoft adds.
The company also explains that it’s already working on a fix for this problem, and this is projected to be included “in an upcoming release.” No further specifics have been provided on when the fix is supposed to land.
