Just by chance, if the other two computers are running Windows XP, try this:
Check the network properties list in the WinXP systems for a component called
the
Link-Layer Topology Discovery (LLTD) Responder. If the LLTD Responder component
is not installed on the Windows XP-based computers they most likely will not be
seen in Vista's Network Map.
Here is a link to an MS fix for the WinXP systems. Note, if they are up to SP3,
the
readily downloadable version (fix v5) probably will not to anything but say that
it is not needed, so then simply request the hotfix patch (fix v6) and apply it
to the
WinXP-SP3 systems.
You must request the hotfix from MS. The how-to information is contained within
the KB article. It will be supplied as a zip file with a time limited password.
After you extract the hotfix patch, simply run it in place on each Win XP
computer.

Good luck!
