Ben, having changed the ZA firewall zone to Trusted Zone, the
ping
worked but still no access to the other computers. However, I
could
print from them (printers are physically attached to the
desktop) so
that was one bit of good news! I then discovered after much
searching
that the workgroup name on the desktop had somehow mysteriously
changed
and differed from the others - so of course that was why I
couldn't
access the data. Now all is restored and everything working
again.
Why these things happen so randomly is a mystery to me; I'm the
only
computer user in the house at the moment, so no-one else has
physically
touched anything (unless it's the cat, which is probably not
impossible!). Other mysteries which PCWorkers may be able to
shed light
on are:
frequent spontaneous rebooting on my desktop computer (XP Pro)
in my
absence - I know it happens because all the progs I was using
before
leaving the computer are shut down;
secondly, the volume control becomes muted every time the
computer
starts up, although I reset it carefully each time. These are
not
serious faults which impede my work, but a nuisance
nevertheless, which
I am lwearning to live with.
Thanks to everyone for all your help with the network problem,
I hope it
won't recur, but in future I shall know what to do.
