So when you lowered MTU to 1452, what test results convinced you to stop
there?

I pinged my defaullt gateway with this
ping -l -f 1452 192.168.x.x
which resulted in a reply from the other end as against the earlier replies
which said packet size too large.
This convinced me to stop there.


There's nothing magical about MTU that says "stop there", as minimum value in
all problem cases.

What MTU references have you read, anyway?


I have read general stuff on the net including those available on the
microsoft website regarding the ways to change the MTU size in the registry.

And have you tried opening any websites by IP address?


Nopes, I have not tried openeinig any website with the IP addreess. Will
that make any difference. If yes how ? Can you explain me the difference
between these two cases.

Well, if your MTU is correct, then DNS is the next good possibility for your
symptoms. Read the immediately above link.

Keeping an open mind, though, you might want to read the first link, and some of
the linked articles. Maybe another article will give you more perspective on
the MTU issue.

Well, unfortunately the problem is not related to DNS, since there is no such
error as 'Can't find the server', but rather that of page getting timed out.

Also , I have checked that I can ping the websites through the command
prompt. So the DNS servers are running fine. In fact I tried to view the
source of the pages while my browser kept trying to load the page, and found
that I get some part of the HTML code for the requested page , but that code
is incomplete resulting in this issue.
:((
Any other lines of thinking !!

Your main diagnosis is "the page is blank with no visible page and ultimately
the page times out". Not a lot of detail there. Remember that I'm not there
with you, all I can do is offer diagnostic possibilities.

But, if you're absolutely certain that DNS and MTU are not causing any problems,
look at LSP / Winsock corruption.

And rethink how you are diagnosing the problem.
