Network problem on XP Home.

[James]

I have a client who has a small network at home. The
network was working fine until about 5 weeks ago when it
suddenly stopped working. He has one machine (COMPUTER1)
which acts as the Host and has 2 LAN adaptors, a SiS900 on
board and a Realtek on a PCI card. The Realtek is
connected to a cable modem, runs with the Microsoft
Firewall and is working OK. ICS is on and appears to be
set up OK. Internet access is working.
The second computer (COMPUTER2) also has an SiS900 on-
board and a Realtek PCI card fitted. One or other of the
LAN adaptors is always disabled as only one is needed.
Both machines have Windows XP Home and have been reloaded
in case there were problems with XP.
COMPUTER1 has the external IP address assigned
automatically and the 2nd adaptor is set to 192.168.0.1.
The Workgroup is the default MSHOME. COMPUTER2 is set to
192.168.0.2. Both have Masks as 255.255.255.0
If I ping COMPUTER2 from COMPUTER1 I get 4 responses <1mS.
If I ping COMPUTER1 from COMPUTER2 I get 4 Timeouts.
If I look at Workgroup computers on COMPUTER2 I can see
both machines but it says Network Path not found if I try
to view COMPUTER1. COMPUTER1 does not see COMPUTER2 at
all even though it can ping it.
Anyone got any ideas???

I ran into the same problem. Had to run the network
setup about 5 times before it all of a sudden started
working. I kept trying other things. Do you have Norton
Internet secruity set up? if so make sure you have the
ip address for the other computer to access the
internet/machine. maybe that is what worked on my setup.

Good point. I know he has the Microsoft firewall active
on the Internet adaptor but I am not sure what else the
client has loaded. Must check for Norton. Thanks for the
suggestion.
