It means Your vpn client can't reach VPN server. Try pinging it to check if server is alive.

Are you using a router/firewall device?
Is the (R)RAS server the same as the Internet Gateway?
Are you using PPTP for VPN connection, or have you setup something special?

Temporarily disable Windows Firewall on that laptop, though it should not block the necessary ports and protocols.
Does it work from other laptops/machines using the same (!) internet provider? I'm talking about the client side, not the server side.

It works with other users ..but not at the same location ..

Enable the logging, and try again. Than observe the logfile, or post it here. As I can see it is a L2TP/IPSec connection, which is pretty reliable usually.
