A few examples:
* I can navigate www.yahoo.com fine - I can even login to my email account, but every time I click on a link to go to my inbox the site times out.
* I can navigate www.dabs.com fine - but if I search for a product it times out.
I've tried resetting my cookies, history and security settings. I've even been in to my registery and adjusted my MTU to 1492 (not sure what this does but I'd seen it recommended to other people with similar problems). I've even reset my Winsock - all to no avail.
The annoying thing is I have 4 accounts on my XP machine. On one of the user accounts (the one which I use for work and goes via my work VPN) does let me access all of the above sites fine, so this isn't a hardware or ISP issue.
Does anyone have any ideas at all what might be causing this?
Oh - also forgot to mention - I get the same problem using either IE6 or Firefox.
