Symptoms

Consider the following scenario:
  • You have a Windows Server Update Services (WSUS) server that is running Windows Server 2012.
  • There is a required authenticated proxy running in the environment. 
  • You enable the Use user credentials to connect to the proxy server setting together with the username, domain, and password provided in the WSUS console.
In this scenario, the WSUS synchronization performs successfully. However, the WSUS server cannot connect to Windows Update to download the required updates. 

Note This issue also affects the deployment of Microsoft System Center Configuration Manager and Forefront Client Services.

Cause

This issue occurs because the system clears the stored network credentials when you enable the Use user credentials to connect to the proxy server setting. Therefore, you cannot connect to Windows Update.

Resolution

This hotfix is also available at Microsoft Update Catalog
