Web Pages won't load/ Win Updates crashes

[Jennifer]

Help?

I am stumped. I got to "windows updates" and the page gets
to the "scan updates" section but when I click on "Scan
Updates" it dies. Won't react at all. I have problems
with web pages not loading or responding.
Even MSN, when I go to mail, will not load my msn mail.

I have run zero-fill on my HD and completely reformatted
and purchased a new Windows XP home full version and re-
installed. I have checked network setting against my
husband's computer (that works fine). I have DSL and my
computer is the main computer on the DSL line. I have
since found in the research that the 3rd computer in the
house is also having the exact same problem. Between
hardware and networking, I can't figure out what else to
do. It seems like it's Microsoft software program issues.

Can't access some web sitesSymptoms: 1) If you're using MS ICS or Windows
server as router to access the Internet, your clients may not be able to
access certain web sites. However, the ICS host or the server doesn't have
this problem.
2) After installed a new router or cable modem replacing dial-up to access
the Internet, you can't access some web sites.
3) You also find that most web sites you can't access are block to ping or
they are security sites using HTTPS.

Causes: 1) The problem occurs because many web servers block ICMP messages
and the packets are dropped. As a result, the requested web site doesn't
load.
2) This problem is caused also by an incompatible MTU networking setting.
You may try to install the latest SP. If you use MS ICS, you may want to
configure all your Client computers to use the new, lower MTU as the default
for all Internet communication. To modify the MTU size, locate the following
registry key: HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\
Tcpip\ Parameters\ Interfaces. If you use a router like Cisco DSL Router,
you may want to adjusting the PPPoE MTU Size. For example, to adjusting the
PPPoE MTU Size on the Cisco DSL Router, do

interface ethernet0
no shut
ip address <ip address> <subnet mask>
ip adjust-mss 1452
