[ubuntu] 12.04 -> 13.04 Networking Issue: Workgroup Password Unknown/Connection Timeout

view story

http://ubuntuforums.org – Hello all! I am very new to ubuntu OS, so please bear with me here. I have just installed 12.04.2 alongside Windows on my system, with most resources devoted to the ubuntu side. I am attempting to share folders with another computer on our home network that is running 13.04 w/out any Windows. As far as I can tell, we've both got samba properly installed to start. More specifically, on my machine (the 12.04) I can see the shared folder from 13.04, but when I try to open it I am prompted for a password that, to my knowledge, was never set up. There are username, domain, and password sections (Hardware)
