Terminal Service Plus

What is the simplest way for HTML5 logged on users to be able to know what their client name is? Can it be displayed on their desktop? Do they need to access the session manager in the admin tool?

ie. .QEJ50XKblahblah.

I know it seems a silly question but we need to know to interface properly with our EFTPOS software.

Hello,

cmd.exe > echo %clientname%
that is the unique id.
