Computers Failing with 80070020 Error RRS feed

  • Question

  • Hello everyone I manage our own internal WSUS server for our organization. We've noticed there are alot of computers failing to check in for updates and its pretty constant now. I've done some digging and tried alot of different things that is mentioned regarding this error code but it doesnt seem to be fixing it. This only started happening recently. I've attached the error logs below from the windowsupdate.log file. Any help would be greatly appreciated.

  • Did you go over this KB https://support.microsoft.com/en-us/kb/883825 ?

  • Yep went through all those steps. Still the same problem

  • As a test on one of those failing computers, can you stop the windows update service, rename the C:\windows\SoftwareDistribution folder to SoftwareDistribution.old for example, start the windows update service and retry scanning for updates.

  • Still no go after trying that. 

    I did just notice the majority of my clients stopped responding the day I upgraded my WSUS to 3.2.7600.274 (KB2938066) 

    Anyway to uninstall this KB/version?

    >I did just notice the majority of my clients stopped responding the day I upgraded my WSUS to 3.2.7600.274 (KB2938066) Anyway to uninstall this KB/version?

    It is recommended to upgrade your WSUS server. If you want to uninstall the KB for test, you may find the KB in installed updates, then right click it "Uninstall".

    Before you uninstall KB, please check if these clients report to WSUS server correctly, check if there are any error in WSUS event log in event viewer. Run server cleanup wizard on the WSUS server and reindex WSUS database.

    Also test if clients could install updates from Microsoft Update.

    Best Regards,

    Anne

  • Anne,

    That's the issue I'm having. Almost 90% of my clients arent reporting at all with the same error I posted above. There are a few that are working fine though. I ran the server cleanup wizard but I have not re-indexed the WSUS database. I will try that but I'm not feeling hopefull. 

    I tried to right click on the KB to uninstall it but you can't uninstall those from what I saw.

    Also this is on a tight airgapped network. The only server that has access to Microsoft Update is the WSUS server so pointing the clients to it wont work.

  • Hi Joe Cutter,

    Have you got any progress after re-indexing WSUS database?

  • I just reindexed. Once it finished I ran a check for updates and the same error is coming up.

    Any other ideas?

    Thanks!

  • This looks like its just the case with Windows 7 clients as well. All of our Servers (Server 2008 R2) are checking in fine. Just Windows 7 failing to work.

  • Hi Joe Cutter,

    Check if update the Windows update agent could work:

    https://support.microsoft.com/en-sg/kb/949104

    Also run reset windows update components on clients:

  • Tried both. Still the same error. I completely rebuilt WSUS and the clients were checking in fine. Soon as I did the WSUS updates to itself and rebooted it broke again with the same errors. Please help!

    Thanks!

  • Did you try updating the Windows Update Agent on a Windows 7 machine to the latest version?

    I think this is the latest version as of now: https://support.microsoft.com/en-us/kb/3161647

  • On one of the machines thats having a problem I just downloaded the July Update (which your's eventually led to because of supersedence: https://support.microsoft.com/en-us/kb/3172605 ) and installed it. I rebooted after installing it and stopped the windows update service, renamed the software distribution folder, and started the service back. I ran a wuauclt.exe /detectnow /resetauthorization and got the same error :(

    Thanks!
