In the WSUS 2012 console, if I go to Updates > All Updates and filter by 'Any Except Declined, Status = Failed' I see that an update (2018-06 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4284835)) installed for 91% of the computers but for some, there were errors. Double-clicking on this line item generates the report, which shows:
For 4 computers the Status = Installed
For 48 computers the Status = Not Applicable
For 6 computers the Status = No Status
For 6 computers the Status = Failed.
Over the last week, I tried a few times right-clicking on the failed update and selecting 'Approve' again, hoping that something would kick in and WSUS would attempt to trigger these updates again. But that doesn't seem to work.
I found some articles online that describe how to run the Windows Update Troubleshooter tool or stop the Service, delete the contents of the update folder, restart the Service and try again, but I imagine there's no automated way to do this. (I'd have to do this manually on each workstation?)
Are there any tricks or tips for getting updates to install?
One more thing: In that WSUS report, I can click on the 'Failed' link under the Status column (next to each of the 6 computers that failed) and a pop-up window shows the error. Almost all of them simply say "Error: Download failed." Does this mean WSUS is not downloading this update? Or it is not able to push the update to the workstation? Or is the workstation trying to download this update? (I thought it should not do that if updates are being managed through WSUS? What would it be downloading?)
All of the computers are on the domain and on the same local network as the WSUS server.
