Windows XP and the DNS cache

[nodnod]

It's just happening on 1 of my computers. Every couple of days or so I can't access certain domains. ie: www.microsoft.com, www.trendmicro.com. If I flush my DNS I am able to access the websites again. Any idea my I need to keep flushing my DNS? I have tried different DNS servers altogether. I am using Windows XP sp3 and this happens in every web browser... Firefox, Internet Explorer, Opera. Any help would be appreciated

Does hitting F5 make any difference?

In IE ->Tools->Options->History settings button->make sure "Every time I visit a page" is selected.

Not at all

Did the second idea help?
And or do you clear your temp file out often?

Sorry I totally missed the second part of that. I do clear my temp files weekly. I'll check my settings at home. I am at work right now so I can't at the moment. I'll let you know how it goes

Your DNS cache gets flushed automatically when you reset/boot Windows. Is your computer being left on?

Something else I'd consider (I mean, I'd do it anyway), is pointing your modem/router to the OpenDNS servers instead of your ISP's.
