Internet Connection Sharing problem

[lklam]

I have recently purchased a notebook and I am now trying to share the
Internet Connection on my desktop PC (which is directly connected to
the ISP) to the notebook via a hub.

While the Internet connection on my desktop PC has always been normal,
I found that I am unable to access SOME of the websites on my notebook.
For example, I can access www.google.com but not hk.yahoo.com. I would
access www.bbc.com but not www.nytimes.com.
I am also unable to access hotmail.com

I have already turned off the firewalls on both of the computers, and
have also tried to use Firefox instead of IE, but the situation
persists.

Do you have any clue about what's happening?

Firewalls aren't causing the problem. Turn them back on. It's
dangerous to connect to the Internet without a firewall for even a
short time.

This is a common problem with shared DSL connections that use PPP Over
Ethernet (PPPoE). Here are some possible fixes. Any one of them
should solve the problem:

1. Install Windows XP Service Pack 2 on the ICS host computer.

2. Find the right MTU setting on the client computers, as shown here:

and then make the setting manually on the client computers, or use
DrTCP to make it:

3. Download the free RASPPPoE program and install it on the host
computer. Use it instead of XP's PPPoE program. Details at these

First check for an MTU setting problem.

Next, check for LSP / Winsock corruption.

Please let us know if any of these suggestions are of any help. What you learn
may help others in the future, and that's the purpose of these forums.

I have solved the issue in just 5 minutes, thanks for your accurate,
helpful and prompt solution.

I would still like to give some more details on my network:
My host runs with win2k, while the notebook (client) runs on WinXP Home
edition.

Your solution 1 and 3 assumed that my host runs on XP and thus are not
quite applicable in my case.

So I followed the guidelines given under solution 2 and solved the
problem immediately.

Actually apart from my notebook, my host also shares Internet
connection with my brother's desktop PC (win2k), which suffers the same
problem in the past. So I simply repeated solution 2 and fixed the
problem.

Thanks for your help!
