ThinLinc has a feature where sessions against Windows Remote Desktop Servers are distributed among several available hosts. In order for this to work, the tl-loadagent service must run on all Windows servers.

For information about which ports are used when communicating with the load balance agent, refer to Appendix A, TCP Ports Used by ThinLinc .

The tl-is-appsession utility allows you to detect if the Windows session is running a full desktop, or just an application. This is done by examining the RDP Startup Shell. When a desktop session is detected, this command returns 1. Otherwise, 0 is returned. This utility is useful in login scripts. For example, it might be desirable to open up a browser whenever a new desktop session starts. This can be done with a script like this:

%ProgramFiles%\ThinLinc\WTSTools\tl-is-appsession
if %errorlevel% == 1 start http://intranet

The SeamlessRDP Shell is the server component required for SeamlessRDP.
