Remote Client Options?
Remote Client Solutions provide technology that form an alternative access method for applications and computing desktops.
We considered solutions based around three core technology groups.

Challenges
Printers
could no longer use Active Directory to map printers based upon computer location
Wrote script to identify name of thin client, wrote to registry and used 2nd script to map printer based upon registry value
Multiple PC Blade Images
Use Altiris SVS to activate certain applications on logon

Challenges
RGS protocol
Symptom of red screen repeatedly appeared on thin clients indicating network bandwidth issue
Analysis revealed it was not switch traffic but CPU load and RGS sender process
Ran Altiris job to change priority of RGS Sender service to high, eliminated majority of problem
New version of RGS has resolved this permanently
