If I understand your question right, you don't want to have to type in your password and press the button to get into win2k?
To do that, what you do is go into 'control panel' and then 'users and passwords'.  In there, you can uncheck the box that says 'users must enter a username and password to use this computer'.  
I personally don't use this because there are people that I don't trust who have accesss to my computer.
