osx 10.2 & Win XP network

HELP! I just got a new 12" g4. I'm trying to setup a wireless-g netowrk w/ my winxp desktop. I set the Personal File Sharing and Windows Sharing both to "On". When I try to "Map Network Drive" in Windows and enter the address the os-x gives me, I get a "Network path ... could not be found". The Powerbook does go onto the internet, so I know that the network is active. Any advise? Oh yeah, the Personal File Sharing access is at "afp://192.168.2.3/" and the Windows Sharing access is at "\\192.168.2.3\ronguzman". (I probabbly just gave everyone my address...)

Any help is appreciated.
