Concerning our earlier blog entry regarding the Windows Update issue we want to inform you, that the july 2016 update rollup KB3172614 is also resolving the issues with KB3147071 andKB3126593.
KB3156418 is superseded by KB3172614 and no longer has to be installed.
Please ignore the warning which is shown on the opening of SG Management regarding these issues if you have already installed KB3172614.
ATTENTION: Windows Update KB3147071 issues problems with the local Windows Firewall of Windows Server 2012 R2.
As Communication Gateway makes use of the local Windows Firewall this also affects CG in working correctly.
Please do not install KB3147071 on operating system instances Communication Gateway is installed on.
In case the update is already installed: uninstalling KB3147071 restores the local Windows Firewall functionality and will regain the full Communication Gateway experience.
Please be sure to disable the automatic update functionality for KB3147071 to prevent future installation.
As the known issue with KB3126593 is still under investigation by Microsoft, please also disable the automatic update functionality for update KB3126593.
As soon as we have further information from Microsoft, we will post an update.
