Help!! ICS(Internet Connection Sharing) goes wrong

{I'm here. So if you posted it, I will reply you as soon as possible}

2. The client computer cannot be online properly by ICS.

It can connect to SOME websites only, not all.

Examples of unaccessible websites:

- www.altavista.com

- www.yahoo.com.hk

- www.sohu.com

and quite a few... etc.

The configuration and settings (very long. You may read some parts only):

=============================================

Hardware and Software Configuration

Main/Host Computer

- Desktop Computer

- OS: Win XP Pro

- 2 LAN (I call it LAN-M1, LAN-M2)

- 1 straight cable is linked from ASDL modem to LAN-M1

- 1 cross-over cable is linked from LAN-M2 to my client computer

- Norton Anti-Virus installed

- Norton Internet Security installed

Client Computer

- Notebook Computer

- OS: Win XP Home

- 1 LAN (I call it LAN-C)

- Norton Anti-Virus installed

- Norton Internet Security installed

ISP broadband company:

- Family 3Mbps ADSL Modem

The setting in "Control Panel | Network Connection"

In Main/Host Computer

LAN network:

LAN-M1

I have clicked the following:

- Client for MS Netowork

- File and Printer Sharing for MS Netowork

- QoS Packet Scheduler

- Internet Protocol

In IP setting:

- Automatically get IP

- Auto get DNS

In Advanced Tab:

- turn on: Internet Connection Firewall

- Clicked: Allow other network users to connect through this computer's Internet connection

- NOT clicked: Allow other network users to control or stop Internet connection sharing

LAN-M2

I have clicked the following:

- {same as above, ie Client for MS Netowork...}

In IP setting:

- IP address: 192.168.0.1

- SubNet Mask: 255.255.255.0

- Default Gateway: {empty}

- Usual DNS: 202.61.98.227

- Other DNS: 202.61.97.235

[The DNS value is from PPP adaptor Family. I found it by running command and input

"ipconfig /all"]

In Advanced Tab:

- Unavailable (ie grey out): Internet Connection Firewall

- Unavailable: Allow other network users to connect through this computer's Internet

connection

- Unavailable: Allow other network users to control or stop Internet connection sharing

Broadband:

Family

In Network Function Tab

I have clicked the following:

- {same as above, ie Client for MS Netowork...}

In IP setting:

- Automatically get IP

- Auto get DNS

In Advanced Tab

- Clicked: Internet Connection Firewall

- Clicked: Allow other network users to connect through this computer's Internet connection

- Unclicked: Establish a dial-up connection whenever a computer on my network attempts to

access the Internet

- Unclicked: Allow other network users to control or stop Internet connection sharing

In Client Computer

LAN-C

I have clicked the following:

- Client for MS Netowork

- File and Printer Sharing for MS Netowork

- QoS Packet Scheduler

- Internet Protocol

In IP setting:

- Automatically get IP

- Auto get DNS

In Advanced Tab:

- turn on: Internet Connection Firewall

- Unavailable: Allow other network users to connect through this computer's Internet

connection

- Unavailable: Allow other network users to control or stop Internet connection sharing

The setup wizard I have run:

In Host computer

- Go to "Start | Program Files | Accessories | Network Installation Wizard"

- Choose "This computer directly connects to the Internet..."

- Choose "the Broadband one" (ie Family)

- Give the computer a unique name (NB: it is NOT the same name as all other comp)

- Give the workgroup a name (NB: All comp use the same workgroup name

- Done!

In Client computer

- Go to "Start | Program Files | Accessories | Network Installation Wizard(網路安裝精靈)"

- Choose "This computer connects to the Internet by another computer..."

- Give the computer a unique name (NB: it is NOT the same name as all other comp)

- Give the workgroup a name (NB: All comp use the same workgroup name

- Done!

Point to note:

- The following message never appears during the configuration of LAN/broadband:

"When Internet Connection Sharing is enabled, your LAN adapter will be set to use IP

address 192.168.0.1. Your computer may lose connectivity with other computers on

your network. If these other computers have static IP addresses, it is a good idea to set

them to obtain their IP addresses automatically. Are you sure you want to enable Internet

Connection Sharing?"

- No matter I enable / disable Norotn Internet Security(NIS), the problem still occurs.

I never make a particular settihng in NIS regarding the ICS and its small network.

Thanks for reading.

Change your laptop's IP address to 192.168.0.x (anything but 192.168.0.1 or 192.168.0.255) and the subnet mask to 255.255.255.0

also, make both the default gateway and primary DNS server "192.168.0.1"

That might help.
