Using Remote Desktop to access the ArcGIS 9.2 License Server (the machine running the ArcGIS License Manager), results in failure to detect the USB hardware key. The following error is returned:
"The SuperPro driver appears to be installed and running. However, the hardware key does not appear to be plugged into a parallel port on this system."
This is a known issue with ArcGIS License Manager version 9.2.
The use of Windows Remote Desktop to connect to a License Server results in the Sentinel driver being unable to detect the hardware key, which causes the License Manager Service to stop.
