Question : Can't access shares on windows home network

I have two Vista PC's with the same user name, on the same sub net and cannot access shares.  Network and sharing shows all the computers are visible, sharing is configured, but when I click on the computer I want to access it says "Cannot access \\AMD-PC" and the same type message for the other computer.
I have had access in the past, but with issues.  The network map on one of the computers shows that it has access through a switch.  I don't have a switch connected.

Answer : Can't access shares on windows home network

It should be this:

(&(objectClass=user)(objectCategory=person)(pwdLastSet=0))
