Connect to a network PC with both Guest and "Bob" accounts, how do

Connect to a network PC with both Guest and "Bob" accounts, how do I force my
pc to log on with "Bob" and it's password instead of using the default
guest...

Vista does not ask for my account and password since it is using the guest
and just spits out an "Access denied" error.

The problem is that i can navigate to the folder with guest but i can't look
inside since normal guest is not allowed to...

Yes. But the PC i'm connecting to is in another building... and I can't
exactly create a User myself since it's not my PC... and I can't tell the
other person My "EXACT" user and password since i don't want the knowing
that...

I got my friend to create me a user and a password .... now how do i do this?!

I've already tried that.... this does not fix the problem...

The bottom line is... HOW do i log on under a specific user name on a
network computer share? Because it logs on under the default lesser username
and i can't switch to the user WITH better rights...
