Remote Network Performance Monitoring

I need to track and record all functionality, connectivity speeds and applications of a remote laptop. Here's the basic set up of my problem:We have 40 medical facilities in five Western States, each with up to 30+ pieces of hardware including thin clients, PCs, laptop computers and wall mounted touch screen kiosks operating on a variety of OS including primarily XP pro, then Linux and transitioning into Win 7.We have installed Aruba wireless network in each building on which our mobile medical cart laptops connect. Each facility has a different mix of primary and backup/failover ISP from DSL, Cable, T1 to Bonded T. All are at or exceed 22MB down, 5MB up save the T1s at their dedicated 1.5 and we monitor speeds and network stats trhough our gateway device. PfSense.All employees connect through an RDP (Remote Connection) to our hosting company in Atlanta, GA where the farm of about 28 servers reside hosting our medical, email and office applications.We regularly are contacted by nursing and clinical office staff complaining that "the network is slow". We review connection speeds, loads, ping times and confirm that there are no ISP Speed issues that are causing the "Slowness". However when we review exactly what the nurses mean by "slow" it invariably turns to how long it takes to log in to the RDP sessions and access then run their medical applications in the RDP. They often sit and wait for the RDP to load for five minutes or more and complain of waiting for their typing to catch up in the applications they work in.

We believe the slowness occurs once they are connected in the RDP and that their problems are occurring at the hosting company's facility, getting through their firewall, through profile management and server hardware/software but we can not prove this is the case because the hosting company always claims they see perfectly acceptable speeds and access on their side and we are locked out from access to monitor tehir environment. Changing hosting companies is probelmatic because they are specialised in our industry and leaving would be diffcult. I need some software that I can install on a few machines in a select few of our facilities that will track and record the actual user experience so that we can watch and review exactly what is happening, what the network stats look like and precisely where the user is experiencing "slowness".
