WSUS Server can't download 1703 Enterprise Feature Update

    Question

  • Hi all, 

    After spending the last day and a half searching online to resolve this issue, I'm posting looking for help. My company is running WSUS on a 2012 server and we are unable to download the new 1703 Enterprise Feature Update it's just stuck at 0%.  I have followed all the steps in the below article. Both updates are installed and manual steps competed, 2012 server is fully up to date. I'm not seeing any errors in the event logs, assuming this is because the download isn't failing just sitting at 0%. I also made sure the .esd type was added into IIS. All other updates which were approved before and after this one have downloaded successfully, this is the only update that won't. Any help would be GREATLY appreciated, I'm going insane over this.

    Thank you, 

    Chad

  • Hi Chad113,

    1. Do you install the KB3095113 and KB3159706 before syncing 1703 upgrade into WSUS server? If not, we need to re-download upgrade file;

    2. Does the WSUS server unable to download the 1703 upgrade file into Content folder, if yes, please check the WSUS event log in event viewer, check if there is error 364, if yes, check the log for detailed failure reason.

    Best Regards,

  • Hi Anne,

    Thank you for the reply. It had already tried to download 1703 prior to me patching the server with KB3095113 and KB3159706. After the updates installed I canceled the 1703 download and retried when it continued to fail I canceled it again, ran WSUSUTIL /Reset and then tried to restart the download and it was still sitting at 0%.

    I came in this morning to find that it finally failed to download and provide me with an error which I copied below.

    Content file download failed. Reason: HTTP status 502: The server, while acting as a gateway or proxy to fulfill the request, received an invalid response from the upstream server it accessed.

    Please check if there are proxy between the WSUS server and the Upstream WSUS server, the event indicates that is a proxy issue. Please ensure the proxy allow .esd file.

  • I verified with my manager that .esd isn't being blocked by our proxy or firewall. Also this is our only WSUS Server so the upstream server then I believe is Microsoft.

  • Hi Chad 113,

    Please check if we could download the upgrade file directly from Microsoft Update without Proxy.
