    Long story short, we have been running an old Windows 2003 server with WSUS and I just fired up a fresh 2012 install. After getting everything set up, I changed my GPO to point clients to the new server. Within minutes, clients started showing up and everything looked groovy. Fast forward a week or two and I noticed that many clients have stopped reporting to the server. In fact, hundreds out of my 3000+ machines are now showing the following errors in the WindowsUpdate.log:

    2017-01-10 07:40:46:815 472 102c Agent WARNING: could not delete Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Services\34b39346-130b-4ae2-8bea-830c8e6c58fb service registry key 0x80070002
    2017-01-10 07:40:46:815 472 102c Agent WARNING: Failed to delete service from the backup store, error = 0x80070002

    I have been able to get a handful of clients to work again by using a combination of resetting Windows Update on the client and installing certain patches manually, i.e. the July 2016 roll-up patch which supposedly speeds up the search for updates. But I have not been able to figure out a real fix for all of my broken clients.

    Does anyone have any idea what could have happened or what might be going on here?

    Hi altbg,

    >Agent WARNING: Failed to delete service from the backup store, error = 0x80070002

    This error is descripted in the following article, you may check if the method could work on one computer, if yes, you may apply it to all affected computers:

    https://support.microsoft.com/en-us/help/910336/windows-update-error-0x80070002-or-0x80070003

    Besides, I would also recommend you run Server Cleanup Wizard on the WSUS server.

    Best Regards,

    Anne

    Thanks Anne, this seems to be the ticket. I wrote a batch file to clear out the Datastore and Download folders and those clients are now reporting and installing updates again.
