I recently deployed a new 2008 R2 server to serve as a Terminal Server (Remote Desktop Services) for about 30 people. The new server is replacing a 2003 server. I expected the new machine to be a considerable upgrade and was looking forward to happy people and less problems. Reality is I am finding several unexpected headaches - discouraging considering the amount of money we have spent on the new machine.
Most of the users connect via HP thin clients, they are the T5510, T5520 and T5530 thin clients. What I have found is performance issues when connecting via these thin clients. I believe the RDP client on these thin clients is RDP 5.5 or earlier. And I do not believe it is possible to upgrade the RDP client version on the thin clients - I guess they are to be seen as "disposable".
The performance issues are: black blocks appearing when connected - and I have deselected bitmap caching - makes no difference. When typing in certain places the display of the typed characters could not keep up with the user. And lastly I have a weird thing that just popped up today; where if the user goes to Google it freezes up their entire environment - I cannot even remote control the user/session - why this came up today and was not a problem before I am not sure.
With all of the above issues I have found that the problem goes away or does not exist if I connect to the server using an RDP client on an XP or 7 computer. So I have to conclude the RDP client is the problem.
Does anyone have information on this? Is there anything I can do as far as configuration on the server to allow me to use these older RDP clients? Do I have any alternative other than buying new thin clients?
thanks!
