MDT WSUS Windows 10 Updates Failing 0x8024401C

Had an issue with MDT failing to install Windows 10 via WSUS. I kept getting the 0x8024401C error.

I upgraded my WSUS on the Windows Server 2012R2 to version 4.0. Then upgraded the host to Windows Server 2016. Still receiving the same error.

After some more googling and trial and error I made the following changes to the IIS server for the WSUS  Application Pool:

  • Queue Length: From 10000 to 25000
  • Limit Interval (minutes): From 5 to 15
  • “Service Unavailable” Response: From HttpLevel to TcpLevel
  • Private Memory Limit (KB): From 18342456 to 0

Build is now receiving updates from the WSUS server.
