Wyse 1200LE and Thin-OS 5.2_069
Thin-OS version 5.2_069 is the latest for the Wyse 1200LE clients, but the problem I'm having is that when I logon to the PNAgent this username and password is not used in my Xenapp 6 session.
There I also get the Windows 2008 R2 logon screen.
We cannot buy new thin-clients because it is too expensive replace them, we have alot of these 1200LE devices.
Is there an another way so that my users do not have to logon twice?
My 1200 devices work reasonably well with XenApp 5. That might be your only recourse since the 1200 devices aren't going to get new firmware.
Another option would be to forgo Citrix and use remote desktop services. If you do this, note the the 1200 devices do not support per device licensing, and they don't play well with the new RD broker in server 2008 r2. Instead of the broker, you can use DNS round-robbin for quasi load balancing.
