Thanks.
The problem is this, the remote machines are 240 and they are around whole Panama. They are giving a robotic service (without human intervention) and using the VPN client to connect to central site. It is possible use RDP but they are too many and sometimes far. The idea is to get a remote procedure to "remenber" or store the PIN of certificates X509 inside the client or the gateway. Do you know how to "remember" the PIN for a certificate?
I know, it is not the idea about to use the certificate PIN but it is a requirement from the customer.
Thanks again.
