Hi all,

I hope someone out there can help me with this. :) I have a home network consisting of a router and two laptops (both XP SP2), one of which is an older Toshiba A8, and the other a newer Toshiba P11. The newly installed P11 is "hangs" when trying to load certain websites (e.g., microsoft.com, walmart.com, linkedin.com). My HijackThis log from both the "good" and "problematic" laptop is given below.

Points to note:
* I have confirmed it is not a network connectivity issue - the sites are reachable from other machines periodically attached to the home network (e.g. a Win2k desktop, as all as the "good" A8 laptop).
* It doesn't appear to be a browser-specific issue, with IE6, Firefox 3.6 and Chrome all experiencing the same "hang" / "black hole" effect when trying to reach the sites on the problematic P11 laptop.
* It doesn't appear to be a problem with the Hosts file or Restricted sites list - checked that.
* It doesn't appear to be a problem with DNS resolution - the sites also "hang" when attempting direct IP address lookup. NSLOOKUP works fine.
* It hasn't been solved by many other posts on this and other sites such as Experts Exchange (e.g. I've unsuccessfully tried http://www.geekstogo...ertain websites )
* If I go through any FREE PROXY available on the internet, it works fine!!

Please help!! It's really frustrating me.

Cheers,
Milo from Melbourne, Australia

Hi folks,

update: PROBLEM SOLVED!! I kept digging and digging (it was infuriating me), and among the various solutions discussed on various other tech support sites, the issue of MTU kept coming up.

So I set it to a lower value (e.g. 576), and voila!

Now if only someone would explain to me why the original higher MTU was causing problems for SOME sites only, but not others? Makes no sense to me.. :)

Cheers,
Milo

DaffyKantReed,

ok, thanks - I think I understand now. Not sure how to mark this as SOLVED?

Cheers,
Milo
