Hi, i've been using backtrack for quite a while but i've enconuntered a problem that i can't seem to solve.

I am trying to connect to my PC (Asus/Vista Home Premium SP1) throught the NETBIOS by using:
smbclient //ASUSGAME-PC/C$ -I
but it then immediatly asks me for a password:
Enter root's password:
But my computer has no password, i have not set up any password. Is there a default password that im unaware of. I've tried a bunch of passwords (default,password,admin,etc.) but to no avail.

If anybody has any idea about this I'd be mighty glad.
