Internet connection sharing on a network

Can anyone help please.
I've had a network running without any trouble on 3 computers for the
past 2 years. I had to reinstall WindowsXP Home on my desktop (the
host on the network) when the hard drive failed. I also had to replace
the hard drive and windowsXP Pro on my daughters desktop when she left
home taking the hard drive with her. My son has a laptop with
windowsXP Home. All conected through a 5 port Ethernet Switch.
Now I've got the network running fine. We can all see each other and
trasfer files between each other. Now we come to the internet
connection. I'm on a 512 broadband connection which runs just fine.
ICS is enabled. I'm the connected to the Ethernet Switch as are the
others.
On the 2 client computers they both say they are connected to my
broadband connection but it is very slow and only a few pages will
actually appear. Most come up with "The Page cannot be displayed".
Neither of the clients can download anything off the net. As soon as
the boot up AVG says the definitions file is out of date. When you try
to download updates it says there are updates to download and then
says "An error has occured when trying to connect to the server. The
server name cannot be converted to the IP address".
I've trawled the net looking for answers but have been unable to find
anything.
Can anyone help or point me in the right direction.
Thanks.
Ian

does everything have the same MTU, preferably 1500 ?
DrTcp.exe can be used to set it, its blank if it is the default value
on the relevant ethernet connection.

Tweakmaster (.com) is a better utility for poking around.

can you ping internet addresses from the client PCs ?

Sorry you gave me no enough technical details to help you.
Maybe you should try to check you TCP/IP settings ( exactly DNS settings )
I could propose you better solution for your network.
Isn't simplest and cheapest to buy some IP router ( like dlink DI-604 )?
No more problems with configuration, every computer is independent from
master computer.

Why are you using ICS - you have a router (or is it just a hub)?
If you have a router don't use ICS - use fixed (local) IP addresses and set
each PC's default gateway to the router's IP address... router does the
connection sharing

Are you using DCHP or static IPs?

What is the default gateway setting?

Do a hard reset on your router...

Can all the PCs ping the router and the ADSL/cable modem?
Can all the PCs tracert to www.yahoo.com or similar?

Thanks everyone for your replies but I think I've got it sussed.

On the host computer under Internet Options/Connections/ Settings I
have an entry under Proxy Server.
proxy.karoo.co.uk and port 8080.

On the client computers under Internet Options/ Connections/ Lan
Settings I put thes in and suddenly everything is working. Apart from
AVG Antivirus. So I uninstalled AVG and installed Avast and everything
seems OK.

Thanks for your replies once again.
Ian

AVG isn't working as it stores the proxy address within itself, rather
than using IE's proxy settings. check your update manager, and add the
proxy address manually in there. alternately, if you reinstall, it'll
pick it up correctly from IE...

Great stuff. Removed Avast and reinstalle AVG putting in the proxy
address and it worked a treat thanks.
