Administrator Guide

In RDP session (RDP 8.1 and later), VOR, H.264, and H.264-AVC444 are enabled by default. To disable these parameters, use the INI

parameter— SessionConfig-RDP EnalbeGFX=yes EnableVOR=no EnableRDPh264=no.

When you connect to an RDP session in Windows 8.1 or Windows 10 with RemoteFX GPU adapter, H.264-AVC444 is used irrespective of

the H.264-AVC444 group policy configurations. If you disable the H.264 feature by using the INI parameter, the VOR codec is used in RDP

sessions. However, graphic-related issues are observed in RDP sessions. The VOR codec is not used when you disable H.264 using the INI

parameter.

TS Gateway in Microsoft Broker

User scenario:

1. Log in to Microsoft Broker with TS Gateway configured.

2. Launch a published collection.

TS Gateway connection is established.

The following table lists the TS Gateway versions supported by Windows Server.

Table 21. Supported TS Gateway versions

Server operating system TS Gateway II TS Gateway III WebSocket

Windows 2008 R2 Support Not support Not Support

Windows 2012 R2 Support Support Not Support

Windows 2016 Support Support Support

• In TS Gateway II or III connection, the setup uses a two half-duplex communication between Terminal Server (TS) Gateway server and

thin client.

• In the WebSocket connection, the session connection setup uses a duplex communication between TS Gateway and thin client

• TS Gateway II and TS Gateway III are downward compatible with Windows Server 2016, that means, if the WebSocket connection

fails or the TS Gateway server or thin client version does not support WebSocket, then TS Gateway II or TS Gateway III is used.

NOTE:

• WebSocket connection log is hidden and not displayed in the Event Log tab. If you want to view the WebSocket

connection log, go to Troubleshooting > Capture and enable Persistent for the export event log.

• From the ThinOS v8.6 release onwards, the WebSocket feature is disabled by default. To enable WebSocket, deploy

the following INI parameter:

Sessionconfig=RDP TSGWWebSock=yes.

Connect to RDP session using UDP with TS Gateway

To connect to a Remote Desktop Session using User Datagram Protocol (UDP) with TS Gateway, do the following:

1. Deploy the following INI parameter to the thin client:

SessionConfig=RDP TSGWUDP=yes.

2. Enable Terminal Services Gateway (TSGW) for the applications and desktops from the Microsoft RDS broker server.

3. On the ThinOS client, start a Remote Desktop Session using the RDS connection broker.

4. Connect to the published desktop.

On the ThinOS desktop, an event log is displayed in the System Information window.
