Launching mstsc.exe using Slingshot and Generic TCP Proxy webApps

Launching mstsc.exe using Slingshot and Generic TCP Proxy webApps

Issue:

The old SSLVPN RDS webApp to launch mstsc.exe no longer works after upgrading to 6.4, due to the Java plug-in going away with modern browsers, and other security enhancements.


Solution:

Create a set of webApps that open a TCP proxy port, and use the new Slingshot application launcher to start mstsc.exe.* **

*This option requires opening the chosen port in the firewall, between the user's workstation and the UW relay.
**SSO is not supported with the Microsoft RDS Client, due to security changes by Microsoft.


Please use the following steps to configure the two webApps necessary to open the TCP proxy port on the UW relay, then launch mstsc:
