ICS problem between 2 XP instances

Pre SP2 I happily shared a DSL connection between FamilyPC (XP Home-Host) and
Laptop (XP Pro-Client). Installing SP2 on Family PC didn't seem to cause a
problem (used AdAware for Spyware). Installing SP2 on Laptop, using Windows
AntiSpyware Beta (subsequently uninstalled) has rendered ICS largely
unusable. Only 'largely', because I can from time to time get a connection
for a short period. I usually use this to update antivirus, etc, but then
the connection drops and I can't resurrect it.
What I want is to be able to share my 'always on' connection all the time.
Thanks in advance for your help.
 
Additional info: Although I can't access the internet via the connection, the
computers are fine for file sharing. Also, the Laptop can't ping its default
gateway 192.168.0.1

Type this command in the Start | Run box on Laptop:

netsh winsock reset

Disable and then enable ICS on Family PC.

Then, run these tests to see if the problem is solved:

1. On FamilyPC, right click the local area network connection and
click Status | Support | Details. It should show:

IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway: none
DNS Server = none

2. On Laptop, right click the local area network connection and click
Status | Support | Details. It should show:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1

3. If #1 and #2 are right, open a command prompt window on Laptop and
enter these lines. Each one should get four replies:

ping 192.168.0.1
ping 216.239.39.99
ping google.com

4. If #1-#3 are right, enter these addresses in Internet Explorer on
Laptop. They should both take you to the Google web page:

http://216.239.39.99
http://google.com

Steve, thanks for that. In short, #1 & #2 are right, but in #3 I was
surprised.
When I pinged 192.168.0.1 all 4 requests timed out. When I pinged
216.239.39.99 and google.com all 4 replied.
I tried #4. On starting, my home page said "This page cannot be displayed",
but 216.239.39.99 came up with google.com. Finally, "http://google.com" came
up with "The page cannot be displayed". Just to be awkward, I tried the IP
address of my homepage (212.58.226.50) and it loaded, but very slowly and
without pictures.

This looks pretty good to me, but I don't understand the significance of not
being able to ping my default gateway. Can you enlighten me?

Thanks
 
Celebrated too soon, I'm afraid. I sat here for a half-hour working on
FamilyPC, then went back to Laptop, which was still running. While I can get
216.239.39.99 I can't get google.com, and when I use the IP address of my
homepage (212.58.226.50) it loads very slowly without pictures - the normal
URL doesn't work. I can now ping 216.239.39.99, but when I ping google.com I
get "Ping request could not find host google.com"

You're welcome, Geiseliam. Please see if these steps solve the
problem:

1. Make sure that a firewall program on FamilyPC isn't blocking pings
and other access from Laptop. Some firewall programs are incompatible
with ICS on the host computer.

2. Specify the TCP/IP settings manually on Laptop:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = your ISP's DNS server

Steve,

No success this time, so I still can't access the Internet from Laptop.
Details below.
#1 I use Windows Firewall on both machines. Following your post I have
amended the ICMP settings for the Local Area Connection on FamilyPC to allow
most things, in particular 'allow incoming echo request', but this has not
solved the problem. I do also have Trend Micro PC-Cillin, but I don't think
there are any settings on that which could stop a ping (please correct me if
I'm wrong)
#2 Looking at the properties of my Public Connection there is no DNS Server
specified (even under the 'Advanced' menu) so I don't know how to determine
my ISP's DNS Server. I've therefore specified manually what was there
automatically, and the ping still doesn't work.

I've tried to repeat the earlier partial success with pinging, but while I
can still ping 216.239.39.99 I can't ping google.com.

Thanks in advance for your help.

#1: Trend Micro PC-cillin includes a firewall capability. Using more
than one firewall can cause problems, so you must disable either
Windows Firewall or PC-cillin. I'm sorry, but I don't know how to
configure PC-cillin, and I don't know whether it's compatible with ICS
on the host computer.

#2: To find the DNS server for the host computer's public (Internet)
connection, right-click the public connection and click Status |
Support | Details.

Steve,

For some reason I couldn't get onto the site for a few weeks, but I managed
to find your post today and disabled each of the firewalls in turn. Both
options seem to work.
Thanks very much. MVP Indeed!!
