I'm trying to map a network drive in Windows 7 Home Premium and it will not connect. I'm using the exact same settings that I used on my other PC with XP and it connects fine. I did some research online and everything I found says you need Windows 7 Professional. Is this correct? Is there no way to map a network drive with Home Premium? The settings I'm using are:

Z: drive - \\192.9.2.25\shared

Username and passsword connect in XP.
They don't work in Windows 7.

Anyone have any suggestions?
