Files are on a server (Hyper-V in this case). Quite literally on each desktop you navigate to the UNC path and do a right click on the main exe and choose send to desktop.
It seems fast when they are closed, but slow when they are open (and everyone is using it). They only have 9 PC's however. The server is way above min and even recommended spec's for the software.
Their network switch is a Netgear GS748Tv5 and I upgraded the FW to the latest version.
