Can't access Yahoo Mail, Windows Update, Hotmail - Internet ok

[Guest]

Hello there,

I have a network of 3 PCs (XP Pro) using 1 ADSL modem and 1 small hub.
Previously 3 PCs can connect to internet and Yahoo mail,...

Currenly 1 PC is ok. The other 2 PCs CAN connect internet, but not YAHOO
MAIL, WINDOWS UPDATE, HOTMAIL.

I try to reconfigure everything, from Disable Firewall, add
http://mail.yahoo.com to the Trusted site in Internet Option of IE, and event
re-install one PC to try to figure out what the problem was, but even
re-install, I still can't use Yahoo Mail,...

Any ideal what the problem was, or how to solve this. Please advice!

Thank you very much.

I've found the solution. All I need to do is to adjust/add the MTU value to
1300 and everything is ok.
