ZTI OSD downloading updates from MS, not SCCM server

[Aurock]

I recently upgraded our SCCM server from 2012 SP1 to 2012R2. Since then, I've been struggling to get OSD working again. After creating a new task sequence, with new versions of the packages for USMT, settings, deployment tools, etc, I've got it mostly back up and going. The trouble now is that the task sequence seems to be downloading updates from windows update, not from the SCCM server.

 

Looking in the SMSTS.log, I see a few errors, though I'm not sure they are related.

During the time that updates are being downloaded/installed, I don't see any errors. Here's the bit of the log file from that time. There are over 600 lines similar to the first few in this example:

Can anyone point me to where I might have gone wrong?
