Thank you for your response!
We are looking at the HP t620s. I have seen various posts and howtos online for getting the NX Client up and running on HP Thin Clients running Thin Pro. They all seem to be using NX 3.5, but you seem to report using 4.x which is great news that it works as well. Would you happen to have any documentation you could share? If not, any gotchas or advise?
The deployment would be using NX 4.x.
