When downloading the Cumulative Update for Windows 10 Version 1607 (LTSB) for x64-based systems (KB4103720), the process hangs up a 9%, then fails. Error Code: Error 0x80073712.
The update is also trying to download the 2018-05 Update (KB4132216) and fails that one also.
I looked back in the update history for this particular remote machine and it appears that this has been going on since October 2017. I have tried to download the update from the Windows Catalog, but that update hangs up when trying to copy the package to the cache.
