WU_E_PT_INVALID_COMPUTER_NAME

WU_E_PT_INVALID_COMPUTER_NAME means the Windows Update client could not obtain the computer name required by the request. This is local identity or configuration information, not a remote DNS lookup failure by itself.

What to check

Confirm that the local computer name is present and that recent rename or domain-join operations completed with a reboot where required.
Check for errors in the Windows Update log that indicate which request needed the name.
If only managed clients fail, compare the device identity and registration state with a working client.
