cannot see computers on home network

[Charlie]

- apologies if this gets posted twice -
I have 3 computers on a home network, Vista Home Premium DT, Vista Home
Premium LT, and XP Media Center DT. Previously all computers could see all
other computers and share files. Today I installed MS update on the Vista
machines, and the Vista DT cannot see other computers nor can they see it.
The Vista LT and XP can see each other. All computers are discoverable and
have shared folders; LLTD is checked.
I system-restored back on the Vista DT but still am unable to see the other
PCs.

Hi
Successful Sharing involves some general consideration in Network settings,

As well as specific adjustment of each computer according to what it is
allowed to be shared.
