I have 5 PC's, four running XP SP2 and one Vista Premium all on a home wireless
network. I can access and share files between the XP systems but cannot
access any of the XP systems from the Vista PC. I have installed Link-Layer
Topology Discovery (LLTD) Responder on each of the XP based systems.
This made the XP systems visable on the Vista network map.

I have network discovery, file, and media sharing turned on. I can see the Vista PC
from the XP PC's and the XP PC's show up on the Vista Network Map. When
I open Network on the Vista PC the only computer listed is the Vista PC. They all have
the same Workgroup name and I do have the Vista PC setup with the Private setting.

Any help would be appreciated
