I have a home network with four computers. 2 are desktops, both running
Vista, both connected by Ethernet cable to a router. The third is a laptop
running Vista, and the fourth is a desktop running Media Center XP -- both
connected wirelessly to the network. The two wireless computers and one of
the Vista Desktops can all connect and access each other. The fourth desktop
can only access the other desktop connected by ethernet cable and the
Internet -- not the two wireless computers.

When I try mapping on the uncooperative desktop, it says Windows cannot
create a network map. It is listed as private, not public, and the LLTD
boxes are checked. When I look at the router software, all of the computers
show up as attached devices. Firewall is not set to block any of the
computers. Not sure what else to do.

Any suggestions?

Can you ping uncooperative Vista by IP?

Weirdest thing. The XP wireless desktop can ping the two wired Vista
desktops -- including the one that doesn't show up on the network. It can't
ping my wireless Vista notebook -- even though I can access media between
them -- it times out.

The notebook gets a general failure when it pings any of the others.

All the computers show up as attached devices in the router software and in
the Trend Micro wireless network monitor.

So confused.

"All the computers show up as attached devices in the router software and in

I think within the Trend Micro programs lies your problems. If you are
behind a router, which you obviously are, there is no need for third party
apps such as this to run/monitor the network. change the default password
on the router and use a similarly strong password on the encryption, and
that is all you need. No SSID hiding or MAC filtering.

Turn off these third party programs, including the services running them to
better evaluate your troubleshooting efforts.
