xp file sharing stopped working

[Bob R]

I have 3 pcs running XP home edition on my home network. Some time recently
my file sharing started acting up. Right now, one of the computers can share
anything but activating sharing on the others does nothing. Bear in mind
that they were all sharing with no problems so it's probably not some basic
configuration thing. When I try to access icons in the network places folder
I get a message that I am not authorized to access the folder. It used to
work. What could have changed? And one of the computers still works fine.
Everything shared on it is accessible from the others. But only the one
still shares. All three are running the same operating system, firewall,
anit virus, etc. I have tried disabling and re-enabling sharing but it makes
no difference. Any ideas??

Thanks

I recently had file sharing problems but it only happened after I briefly
lost the wireless network connection. When I got it back on I had to reset
the entire network in order by unplugging the modem and the router, then
turning off the pc then turning them back on in order to restart the
network. If you haven't done this since the file-share has stopped you might
need to unplug and reset the network.
There is also a special networking newsgroup that may be able to help more.
