Update on the T50
For any that may come across this thread and would like an update ... here you go. Wyse did replace all of our T50's. The new experimental image they were working on to help alleivate the issues reported by all in this thread did not help. Wyse replaced the T50's with the C50LE. The C50LE units we recieved have been working flawlessly for well over 6 months and the client is happy.
That said we are no longer using the session broker capability. We have two terminal servers. We place two RDP icons on the desktop of each thin client. One says "Login" and the other says "Backup Login". The RDP files are configured 50/50 so half the thin clients primary login is to Term1 and the other half primary login is to Term2. If for any reason a terminal server has problems the protocol calls for the users to launch the "Backup Login" RDP file that will connect them to the other server. Not optimal, but we had no faith in the session broker working with the Wyse Linux OS (our session broker setup worked perfectly with Windows XP/7 desktop clients and Microsoft Tech support confirmed it was setup correctly...after all it's not that hard to setup, and there are dozens of walkthroughs). As for RD Gateway support we still have a ticket open with Wyse. The option is implemented on the C50LE ... but it does not work. Luckily we don't have to have that feature since all the installed units are on a LAN.
Now if you want my advice here it is. Get the HP T510. It is $345 at Provantage. It runs Windows 7 embedded. It is absolutely fantastic. Full RDP 7.1 + RemoteFX support. If you want to use all the new RDP features of Server 2008R2 or Server 2012 do yourself a favor and buy a thin client that runs Windows 7 embedded. I just setup the HP T510 to use Terminal Server, Session Broker, and RD Gateway in 5 minutes and it works flawlessly.
I am having the issue with Wyse Enhanced Suse Linux whereby the session freezes on the screen. After doing much research I have found people experiencing the issue with the same client as me, the Wyse D50D. However I can see others have the exact same issue across the range. I am using a Citrix backend, I do not believe this is a Citrix issue as I can always reconnect to my session from a different terminal or if I reboot the problem terminal.
I have noticed my freeze time coincide with DHCP renew times, I was able to accurately predict freezes by working out when the release would next renew. Please remember when checking this, the client will check the lease at 50% of lease time. So if you have an 8 hour lease you could have the problem every 4 hours.
I’ve since started using static IP’s on terminals to try and prove it’s a DHCP issue, however one user has reported a freeze with a static IP
Thanks for sharing this useful information. This is very helpful while occur error.After studying two of our users who seem to experience very few issues we realized that these two users use Microsoft keyboards and mice rather than the Wyse keyboard and mouse that come with the T50.Further testing on other units with various keyboard/mouse combinations shows that if you replace the Wyse mouse with a third party USB mouse the terminal will lock up much less.
