After i sent to sleep my PC, and wake it i cannot connect to PPTP VPN, i got error 633. I don't have any modem, and i use direct link internet (without any VPN). I tried different drivers but no luck. And i notice that rasman service become unmanaged after my PC wakes up. Thats the reason, if i stop rasman before the PC sleep then after waking up VPN works. Any thoughts ?
