Resolved Can't Connect to Networked Computer

Running W7 HP 64Bit on all PCs. On one of them I get a "Enter User Name and Password" screen when I try to access it. All others are ok. The problem PC has a new W7 install. I've tried all available sharing options and confirmed it's in my Homegroup. I didn't create a password during the fresh install.

Any ideas?

 

Nevermind I had a senior moment. I did use a password in the installation. Found it in the credentials app. It listed the computer's name (User Name) and fortunately, the number of astericks indicted for the password led me to believe it was the simple password I use for all new installs.
