Hi Nishad
Apologies for the misreading of your earlier post
So you wanting help using WinGate VPN? and want to access the XP machines behind the Windows 2000 host is this correct?
Have you completed the WinGate VPN setup?
I presume that you have configured the Win2000 machine to host a WinGate VPN and exported the configuration file to your remote machine that should also have WinGate VPN installed (as per WinGateVPN help file).
After importing the Vpn config file into WinGate on the remote machine you can then connect to the Win2000 machine and if you have configured it to allow access the rest of the XP machines on the LAN behind the WinGate? (By setting the VPN config participation to Local Network).
If you are connecting successfully what do you see in the network configuration tab in Gatekeeper on your remote PC does it show the host machine ( with XP machines behind it) ?
