Detailed Description The PC Anywhere service does not require a password to access the desktop of the system. If the system is running Windows 95, 98, or ME, gaining full control of the machine is trivial. If the system is running NT or 2000 and is currently logged out, an attacker can still spy on and hijack a legitamate user's session when they login.
