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.
