I guess I got a laptop which is beyond IT's support. It has 8G ram, so I chose to use Windows 7 64-bit OS. Everything is fine except the VPN connection.
Since IT is not going to support this non-SOE image, I find another way to get the .sdtid token file which, I believe, is used by RSA Secure ID Client.
Can someone tell me what software I need to install and how to set it up? I heard Cisco VPN Client does not support Windows 7 64-bit OS.
