Networking failure again

[Peter]

I am posting this again as the thread was dropped.

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??
I cannot ping one or the other by name or IP. 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 my machine -- it is a simple home network.

Do you have 3rd party security software? For troubleshooting, you may want
to try clean boot. This how to may help.

Hi
Maybe this can Help, make sure that the Software Firewall on each computer
allows free local traffic. If you use 3rd party Firewall On, Vista/XP Native
Firewall should be Off, and the active Firewall has to adjusted to your
Network IP numbers on what is some time called the Trusted Zone (consult
your 3rd Party Firewall instructions.

I do have 3rd party security -- Trend Micro Internet security 2009 -- I have
Windows Firewall off and use the TrendMicro. I have turned all firewalls off
and it still won't let me in -- I have felt it was a firewall issue with the
TrendMicro but have not been able to find the right place to check those
settings -- I will have to delve into that a lot more and maybe I can get
back to you......thanks
