Hello,
I have came into a very strange problem. I have created a PPTP server for VPN. Made some secrets, address pool 192.168.100.0/24. The problem is everytime i connect on Windows 7 computer i can see connect and ping server which is on 192.168.1.200 (192.168.1.10-192.168.1.180 local DHCP server). But when i do it on Windows XP computer there is no way i can even ping that server nevermind connecting to it via RD. Even if i use the same secret account and ip. Any help would be appriciated because im in a deep hole 
Thanks Guys
