Problem in sharing internet connection

Hello,
I've got a problem of sharing internet connection for two computers. Both
machines run Windows 2000 Pro.
I connected a laptop with a desktop via ethernet cards. Both are in the same
workgroup and can see each other. The laptop has another ethernet card
connected to an ADSL modem, using PPPoE protocol. I followed the
instructions in Windows 2000 help to allow both machines to share the same
internet connection. The internet access from the laptop works just fine.
However, the desktop can hardly open any web pages. The message at the
status bar reads "website found. Waiting for reply ..." then waits forever
until I stop it mannually. Interestingly, the desktop can open
www.google.com.au page and do search there but not further more. I can also
send out emails from the desktop successfully but can not receive any. The
desktop can ping whatever IP address that the laptop can. From what I just
described, can anybody offer some help? Thank you in advance.

Sounds like it may be an MTU issue.

To check the MTU size:


1. Start a command prompt, and then use the Ipconfig utility to
determine the default gateway of the Internet Connection Sharing server.

2. At
a command prompt on a client, type the following line, and then press
ENTER:

" ping -f -l <MTU_size default_gateway_IP_address>" (without the
quotation marks) Start with an MTU size of 1,490.

3. If you receive an error message that indicates that the message must
be fragmented, repeat step 2 by using a smaller MTU size. Repeat this
process until the ping command succeeds.

Thanks! Marc,
I modify the MTU size to 1470, following the instructions on Microsoft
Knowledge Base Article -- 283165. Unfortunately, the problem still remains.
Any other solutions?
