Networking failure

[Peter]

I have three computers on my home network -- two wired and one wireless. Two
run XP Pro and one XP Home. I suddenly can no longer log on to the home
network with the two XP Pro machines and yet all three go out through the
router to the internet via cable without problem. I have re-installed
networking with the Wizard, re-installed the networking card, reset the
router -- I get the same message on each to the effect "you don't have
privileges to access the network".......any thoughts please??

Can they ping each other by name? If not, can they ping by IP?

No -- neither computer seems to think it is on the network -- the other XP
Home machine cannot see either of them. I have no trouble going to the
internet through the network and I can address the router via internet
explorer. Basically the message says that I do not have permission to enter
the group which is name "MSHOME" at present, though I have tried name changes
of the workgroup when I have done re-setups of the network to try to solve
this. It says:
"Mshome is not accessible. You might not have permission to use this network
resource. Contact the administrator of this server to find out if you have
access permissions.
The list of servers for this workgroup is not currently available"
I am the Administrator of may machine -- it is a simple home network.

This sounds like the firewalls are blocking ICMP packets. Have you enabled
"file and printer sharing" in the firewalls?
