Troubleshooting a Thinclient Network

I have a network that uses HP5565 thinclients to access their data from 2008r2 Windows Server.
My problem is that users are complaining that when they use large graphic files, their system stutters as they click around the document . This problem does not exist on Thick clients on the same network. Does anyone know of way to troubleshoot this problem? Is it the HP thinclient, network, or both?

I think you have answered the question yourself, don't you. If the thick clients on the same network are not have this problem, but the thin clients do then that must be it, don't you agree? Can you add additional RAM and test of that fixes the problem?

That is the consideration.  But before I ask my client to purchase more ram, how can I determine that adding more ram will fix the problem?

Do you have small graphics files? Test with those and see if the response is better. You can also run Task Manager and see how much RAM is been used without opening the files, how much is used when you do and how much the pagefile (harddisk temp RAM) is used. Performance Monitor can also be used to see what resources are been used when you opnen these big graphics files.

The problem does appear to be hardware related. But one local techie, suggested that consider that the RDP(Remote Desktop Protocol) may be a contributor/source of the problem. I am checking that out.

Aren't you using terminal services to connect your thin clients? Or are you using remote desktop and how are they connecting?

I am using "Remote Desktop Protocol" and Terminal services with my HP 5565 to connect to Windows Server 2008r2.

How much RAM do the thin clients have and how do the thick have? What about pagefile sizes?

Well that is more than likely the cause--I can say with a great degree of confidence that more RAM will help, Win7 has a 1GB requirement for 32 bit and XP 512MB and since this is happening when they are using "larger" files there is probably a memory issue. You could test it without buying new RAM by using spare RAM or RAM from another system and bump the thin client RAM to 2GB and then test opening the files and see if the problem is resolved.
