Latest Updates

Dear Customer,

We would like to bring to your attention that due to the latest Microsoft’s changes in the implementation in the RDP Protocol delivered with Microsoft Windows Creators Update, the use-case scenarios involving Balabit Shell Control Box and usage of Remote Desktop Gateway (formerly known as Terminal Services Gateway) will experience connectivity issues.

Affected systems: all enterprise infrastructure that use Windows 10 client machines, plans or has installed the latest Creators Update patches and audits its RDP traffic with Balabit Shell Control Box through RDG/TSGW. Native RDP connections are not affected.

Effect: after applying the update by Microsoft, no RDP connections can be established through SCB.

Workaround: No global workarounds are known yet. We are in touch with Microsoft to identify one.

Timeline, action plan: Currently, we are investigating the issue and we will provide update on any identified workarounds and on the delivery of the fix as soon as any further information is available.

Advice: In the meantime, we advise to postpone the rollout of the Creator’s Update in your inftastructure until a workaround is identified or a release of a fully compatible SCB version is installed. If you have already applied the update and experience the connection issues, please report the incident and we shall try to identify any environment specific workarounds. If you have any questions regarding the case, please do not hesitate to turn to us.

Apologies for the inconvinience.
