NETWORKING ON XP professional
 

I setup networking with 2 PCs. A PC user account name is 'RMS00' and the
other PC user account name is 'RMS11' with no password. I have no problem to
share files between two PCs, but I have to type in user name either RMS00 or
RMS11 once at the power up when I want to look the other PC's file. After
first file is looked, PC does not ask to type the the other PC's user name.
How can I set up a network without asking user name for other PC when a PC
is powered up?
