Description Thomas 2018-03-21 06:00:13 UTC

Hi, i updated my Windows server 2016 with this Windows Update 
2018-03 Kumulatives Update für Windows Server 2016 für x64-basierte Systeme (KB4088787).

After this KRDC 17.04.2 can not connectet to the Server over RDP, i think it like a Problem with this changes in the CretSSP https://support.microsoft.com/en-us/help/4093492/credssp-updates-for-cve-2018-0886-march-13-2018

I can confim this behavior!
Trying to get an RDP-Session from KRDC to a actual Windows-Srv. is not successful.
(Useing an openSUSE 42.3 full patched with KRDC 17.04.2)

The Problem is still the same with OpenSuse Leap 15 and KRDC 17.12.3

Yes, it seems that this looks like the same problem.

Comment 5 Thomas 2019-02-17 17:38:40 UTC

The Problem is still there with krdc 18.12.1 on Opensuse Leap 15.1
