ConfigMgr 2006 Hotfix KB4575790

The ConfigMgr 2006 Hotfix KB4575790 is now available. This update fixes an issue where client setup fails to download contents from a cloud distribution point.

There have been lot of ConfigMgr 2006 hotfixes releases. In a way it’s good to see Microsoft patching the issues quickly. However I feel that when there are too many hotfixes, it is bit confusing when it comes to installing these hotfixes.

The hotfix KB4575790 address the following issues.

  • When a cloud management gateway is configured to use a cloud distribution point, ccmsetup.exe fails to download the client installation file ( from Azure blob storage. This leads to increased CMG traffic. It also delays installation or upgrade of the client because it will fall back to use another management point if available.
  • Internet-facing clients that only use PKI client certificates for authentication fail to install or upgrade after you install KB4578605 update rollup.

KB4575787 – 404 Error

Anyone who clicked hotfix KB4575787 link experienced 404 error. The link is now accessible with the below note at the start of the article.

The update 4575787 is superseded by the following update. KB 4575790 – Client setup is unable to download contents from a cloud distribution point in Configuration Manager current branch, version 2006.

Microsoft decided to supersede KB4575787 with a new hotfix KB4575790. So why was KB4575787 removed ?. Probably Microsoft would have discovered an issue with that update and hence they decided to release a new update.

Moreover the ConfigMgr 2006 update KB4575787 was a out of band hotfix. That means you had to first download 4575787 and import it in the console using the update registration tool. Where as with KB4575790, you don’t need to import as it is available in SCCM 2006 console.
