Any answers?
I have XP sp3 on all three computers. I have a 802.1 N router (linksys). I
run ZoneAlarm Free Firewall.
I ran the wireless network setup wizard. All computers can connect to the
internet through the router.
I ran the network setup wizard, shut down, restart and can see and share
files and printers from and between all three computers. So my network is
fully functional? No...
Then I leave them for a short while and the shared folders disappear and I
get this error message when I click on a listed shared folder from another
computer: "\\PUPPY(one of the other computer's names)\My Documents is not
accessible. You may not have permission to use this network resource. Contact
the administrator of this server to find out if you have access permissions.
The network name cannot be found.
Things I have tried:
A. I checked that the network name is the same on all computers. (It must be
coz it worked already but I still checked)
B. I set the firewall to accept an IP range which covers all the computer's
IPs in the trusted zone i.e. those IPs are accepted.
C. I tried with no firewall on any computer at all. Still no joy.
D. I tried to run network wizard again, restart on all computers and hey
presto, the connections are all there again.

Question: Where do the connections go? Why do they turn off? Are they timing
out? Is it magic or voodoo? How do I nail this problem?

Thanks to anyone who replies in advance. You people rock. And smile at
someone new today. It works.
