i'm building Remote PC Control s/w. See i'll receive text message like -

login userid passwd

from a Remote PC.

so i need to login,logoff that remote user to the system if user account is created in the Operatin System for that user.

e.g: login Administrator passwd

Administrator account must exist in User Accounts
