[H] XP Pro asks for password when mapping drive

[Thane Sherrington]

I have two XP Pro machines.  I'm sharing a folder on one and mapping 
it on the other and drive N: - it wants a username/password (which 
has to be entered each time.)  I know I've setup XP Pro like this 
where it just remembered the password and didn' t prompt 
everytime.  How do I do this so it just maps on boot up and doesn't bother me?
