Problem using Smart Card Reader with Remote Desktop Connection

[Guest LoveDivineMother]

We have problem using smart card reader when Remote Desktop connection is

made.

 

Our application (running as windows service) uses smartcard reader. This

application is installed on Machine A (Windows XP).

Smartcard reader is connected to Machine A itself. Normally application is

able to detect & use smartcard reader.

If we connect to Machine A from another Machine B (also Windows XP) via

Remote Desktop Connection, the application on Machine A looses connection to

smartcard reader. This happens only when RDP connection is made.

To rule out possibility of problem in our application, we tested smartcard

reader with a Smartcard test utility (SmartPCSCDiag.exe) from SCM Micro. This

utility is also not able to detect card reader when RDP connection is there.

It seems that Smartcard Resource Manager is stopped/disabled by windows when

RDP connection is made.

I have following queries:

 

1. Does RDP connection really have impact on Smartcard Resource Manager

functioning?

2. If yes, what is the workaround/solution to this problem?
