Do you have IP connectivity before attempting to connect to VPN? I assume there is no problem with IP connectivity but if this is not the case, that would be the first thing to sort out.

Have you got all the bits that you need to connect to the VPN server / concentrator:

Security token / one time password
VPN Server IP
Username and Password

What VPN client are you using? Assuming there is no issue with your PC / OS etc.
