What’s New?
We have a pre-req!
“To apply this update, you must have Microsoft .NET Framework 4.5.2 (Offline Installer or Web Installer) installed.”
Some new commandlets have snuck in as well:
- Get-CsAdditionalInternalDomain
- New-CsAdditionalInternalDomain
- Remove-CsAdditionalInternalDomain
- – and no, in case you think I’ve missed it, there’s no “set-“
It doesn’t appear to have made its way into the online documentation or offline help yet, so for the time being it might have to remain a mystery…
Download
Installation
Here’s the “before” view of it going on to my Lab’s Standard Edition Front-End:
Reboot?
The installer didn’t prompt me to reboot, but I always like to give it one for good measure!
Revision History
14th December 2017: This is the initial release.

I noticed for the download that it contains a “UcmaRuntime.msp” also this time. Do you know what is it used\needed for? Most CU’s only have the .exe installer, but this one has the msp file.

Exchange (UM) is the most obvious place, but it’s worth checking all the Trusted Apps in your topology.
Hello Greig
Hopefully you can answer my questions.
Our Skype for Business 2015 [CU4HF1] environment:
2x EDGE, 3x Frontend, 1x SQL
Do you recommend to install .Net Framework 4.6.2 or even 4.7? Because it is supported:

Will CU6 fix the problem with the May 2017 .Net Framework security update?
I mean, do i still have to request new Edge Internal and
Frontend Pool Certificate with Client and Server Authentication to avoid this problem?
Article about this issue: https://goo.gl/nSwXjl
So far I only installed all .Net Framwork security updates till April 2017
Best regards,
Ihsan
CU6 does not fix the issue, tested
Hello Marars
Thank you for your response.
Ok, I will request a new edge internal and a front end pool certificate with client and server authentication.
Hi Marars,
I think CU6 only band-aids the issue. It looks like it just adds the registry key referenced in the issue’s KB as “Workaround 2”. (It may do more than that of course, but the registry key is a visible change).
