PXE Boot failures or task sequence delays after updating to Configuration Manager current branch, version 2002

Applies to: Microsoft Endpoint Configuration Manager (current branch – version 2002)


After updating to Microsoft Endpoint Configuration Manager current branch, version 2002, operating system deployment task sequences fail during the PXE boot process. This occurs more frequently in environments with a large volume of packages in the task sequence. 
The SMSPXE.log file will show a time difference of 30 seconds or more in between corresponding Operation: BootRequest and Operation: BootReply entries. There are no explicit errors recorded before the boot process times out.
In addition, the Resolving Task Sequence Dependencies process of a task sequence may take considerably longer than expected when multiple dependencies are present. 

In both cases the CPU of Microsoft SQL Server on the site database will show higher than expected usage.
