One of my employees recently got a CAC card and a USB reader.

The reader works fine, and I can see the certificates if I open IE9 and go to Options > Content > Certificates > Personal.

When I go to a DoD website (Internet Explorer JPAS) and click the CAC button, a dialog comes up with the different certs. I select DOD CA-25, type in my PIN and then the webpage errors out. (Internet Explorer doesn't give very good error reporting, but I think it was error 103.)

If I repeat these same steps from my home PC, everything works fine with the same reader and CAC.

What's going wrong at work?

**Updates:**

* The error given by Chrome is "error 107"
* I'm running Windows 7 64-bit
* I get the same result with my Cherry st-1044u as my cheap cl-ud-200 63-in-1 card reader; both readers work perfectly on my old machine
