This same key works just fine on my Linux boxes when I use it for authentication between them but not in Windows. PuTTY shows no keys available in the agent and thus my login is rejected.

I don't know exactly about getting the original gpg-agent to run on Windows.
But I know for sure that it works with a GnuPG card under Windows if you
use the
SmartCard-Auth [ http://smartcard-auth.de/ssh-de.html ]
But beware that you need to register (and pay a small amount) with the
/actual version/ of this software...

Salut, Joerg
