Software Update Services does not resubmit proxy request with credentials if anonymous request fails
Article ID: 830700 - View products that this article applies to.
When you try to synchronize your Microsoft Software Update Services (SUS) host with the Microsoft public Windows Update site, you may receive the following error message:
Manual Sync Started- Date and Time Failed
Failed to download from URL 'http://www.msus.windowsupdate.com/msus/v1/aucatalog1.cab'. (Error 0x80190194: HTTP error 404. The system cannot find the file specified.)
Sync Finished-Date and Time
This problem may occur if you have installed the hotfix and added the registry keys that are described in the following Microsoft Knowledge Base article:
297324The problem occurs because the SUS Synchronization service does not retry proxy connection requests if the proxy server does not send a "Proxy Authentication Required" error message. Although the proxy credentials are set, the SUS Synchronization service first tries to use an anonymous request. When the call fails with the "Proxy Authentication Required" error message, the service submits the proxy credentials. Otherwise, the SUS Synchronization service does not submit the proxy credentials.
