• KB 4025331 for Server 2012 and KB 4025336 for Server 2012 R2 breaking WSUS and SCCM

    Summary from Günter Born on his BornCity blog.

    • KB 4025336 blocks the client’s connection to WSUS

    • After installing KB 4025331, no more Office and Windows updates could be installed from clients via SCCM.

    In both cases, uninstalling the updates solves the problems.
