I have 3 Windows 7 PCs on a network with 1 Ubuntu server 13.04 machine running Samba. I can get all of the PCs to show up together and I can get all of them to show up on the Ubuntu Server machine. But for some reason I cannot get the Ubuntu Server to show up on one of the Windows 7 machines. I am very new to Ubuntu and not using a GUI, so any ideas would be greatly appreciated. Also, I already searched the net on this issue but I don't think the answers I found really apply to this problem since it's only one PC that is not connecting. Thank you.
