XP wireless laptop shows up in Network Map, but not in Network

From the XP laptop I can access files on Vista desktop, but I can't get to
the laptop from the desktop. Laptop shows up when I map the network, but I
can't access it. It doesn't show up in the list of computers and devices.
Firewall and antivirus are disabled on both machines. What am I doing wrong?

Curiously, I am having exactly the reverse problem. From the Vista desktop
have full access to the XP laptop, but from the laptop I have no access to
the Vista machine. Even the shared printing that used to work transparently
from the laptop when both machines ran XP no longer functions.

Tech support spent a very patient hour or more with me and was unable to
resolve this.
