Issue Reported: Windows update patches catalog is showing in software center but unable to download.



Step 1:  Fixed the problem by enabling “Allow clients to connect anonymously” on the site in the ConfigMgr management console: Administration -> Distribution Points.

Step 2: Enabling Windows Authentication in IIS on the distribution points that are being affected.

  • Open IIS Manager and navigate to the level you want to manage.
  • In Features View, double-click Authentication.
  • On the Authentication page, select Windows Authentication.
  • In the Actions pane, click Enable to use Windows authentication.
