Cannot connect via VPN

Hi
I am trying to connect a remote user via vpn to the company network, but its not working. From the same computer I am able to make the vpn connection with my login to the same network. I was thinking the problem will be the user login profile so have deleted login profile and recreated I get this same problem. It does not give any error when I type the password in vpn login window it just goes blank the password filed after 4 attempts it give 433 error connection terminated by peer( Reason Not specify by peer). I use windows XP.

Thanks
