2 Network questions; Please help!

Hello,

I have one Notebook computer and one Desktop Computer on a home network
using a Net Gear router. The desktop is hard wired to the router and the
notebook is using it's internal wireless card. Both computers are running
Vista Home Premium; completely updated to the best of my knowledge.

When I make a connection from my Notebook to the Desktop Computer through
the Network for the first time each day I have to type in my user name and
password I use on the Desktop PC. Each time I do this I check the box to
remember this information, but it never does.

Second; is there away to set a password to access my Notebook through the
Network without setting one to log on to my Notebook? I am the only user of
my Notebook so I really don’t need a password to log on. Plus I don’t want to
assign one so when I boot the Notebook it will go right to my Desktop. The
problem is there are multiple users on my Desktop PC and I want to be the
only one to be able to access my Notebook. I set the Notebook to need a
password to access it through the Network. When I try to access the Notebook
from my Desktop it asks for the user name and password like it should. I am
using the user name for the Notebook, but I don’t know what to use for the
password. I tried leaving it blank and I tried using the password for the
Desktop, but neither worked. Can someone help me with this problem?

Any help would be deeply appreciated!

Thanks, James
