No access to some popular sites from some PCs

[Slam]

Small workgroup of six PCs, small switch connected to broadband router.

1. On some PCs I can access all web sites without problem.
2. On others I can access some sites but not others, e.g. I cannot access
www.epson.com, www.msn.com.
3. One of group 2 is a laptop - take it to another site and it works fine.

You could say it is IE6 setup /security but point 3. suggests that isn't the
case. Anyway, I've been into IE options, advanced tab and clicked on Restore
advanced settings. I've also cleared all history.
You could say the broadband/router settings are blocking sites but why
randomly and anyway some can access but others cannot.
It's driving me nuts! Any ideas, please?

Thank you.

Define "cannot access".

What happens when you try?

Nothing. It just sits there, with no response - neither 'waiting for...' nor
'cannot display web page'; no progress bar even.

If you let it sit for a long while, does it eventually fail with any kind of
message?

Is the IE6 throbber icon (the globe or Windows logo) in the upper right-hand
corner spinning/animating endlessly?

Can you access these problem pages using a different web browser (e.g.
Firefox)?

Make sure your proxy settings are correct (Internet Options - Connections -
LAN Settings). If you don't use a proxy, make sure all of the checkboxes on
this page are unchecked. On the Connections page, make sure Never dial a
connection is selected and click OK.

Check your security settings, make sure these sites aren't in your
Restricted Sites list, check your HOSTS file, check your firewall settings --
try DISABLING the firewall temporarily...

What firewall/security software are you using?

I am delighted to say that I have, this week, come across a fix. The problem
appears to be the modem/router, which is a Belkin. They don't yet have a
firmware update but the workaround requires running a small program called DR
TCP. It doesn’t answer the question as to just why this suddenly started
happening but it resolves the problem.

Thank you for your suggestions.
