What are the issues with KB3148812 update

The WSUS team had already published in their earlier blog on TechNet that their latest KB3148812 update has some known issues. The KB3148812 update was released earlier last week. As soon as the WSUS users installed the updated, their WSUS admin console became inaccessible. Besides, some users received the error saying, ‘clients can’t contact WSUS’. However, this blog of initial fixes offered by the team for this issue seems to have been pulled by Microsoft.

On April 22nd, Microsoft published yet another blog on this issue with the title as Part 2. The team has mentioned the facts about the KB3148812 update.

  • KB3148812 requires some manual steps to complete its installation
  • Failure to perform these steps leads to two issues: loss of WSUS console and client scans against WSUS
  • Performing these steps (as listed today) fully resolves the WSUS console issue
  • There is a chance that you will see client scan failures even after performing the steps

The team has further mentioned that this update contains critical functionality that needs to be in place before the Anniversary Update. However, it does not need to be installed this week as there is no security fix that patches a known vulnerability. Hence, the team has recommended some other steps:

  • Until further notice, if you have not already installed this update, do not install KB3148812.
  • If you have installed it and not yet performed the “wsusutil postinstall” step, then uninstall KB3148812.
  • If you have installed it and have already performed the manual steps recommended in a previous post, then please Email Blog Author so that we can work directly with you
