When attempting to install the ConfigMgr client on a computer error ‘Failed to download client files by BITS. Error 0x80080005’ is seen in the CCMSetup.log file.

The BITS service is stopped and gives an error when trying to start it.

When checking the System Event Log, the following error occurs for the Bits-Client source with event ID 16392.

The BITS service failed to start. Error 0x8E5E0226.

The fix, as found here, is to remove all files from “C:\ProgramData\Microsoft\Network\Downloader”, then try to start the BITS service.
