My ISP is stumped, Dell's tech support is stumped, *I'M* stumped, hopefully you guys can help.

I'm having problems connecting to some websites - I can load some without any problems, and can't reach others. I can load Google.com just fine, but can't connect to any of Dell's sites. Microsoft.com works, Support.microsoft.com does not. Tried IE, Firefox and Netscape - same problem with each, so it's not a browser issue. Hooked another PC up to the modem, and it's working fine, so the problem isn't with the modem or my ISP, which means something's wrong with the PC. Turned off, then uninstalled my firewall - nothing. Cleared cookies, cache, reset network connection, still nothing. Re-boot in safe mode with networking, after shutting off all third party startup and system apps. Nothing. Open a DOS prompt to ping sites I can't connect with, nothing - pinging the URL times out, pingng IPs time out. Network card seems to be running fine per the device manager. Just ran Ad Aware and Spy Bot, nothing particularly offensive - a couple of tracking cookies. AVG *just* finished its scan, nothing there either. Ran HJT and nothing's really jumping out at me from the log but then, I'm not an expert, and would definately appreciate a second look:

Problem solved. Looks like it was a malfunctioning NIC - troubleshot every concievable alternative flushing DNS, TCP/IP, factory restore of Windows and software... nothing worked; tried plugging in a backup and hey-presto, everything's loading fine.

Seemed a really unlikely problem - you'd think if the NIC was fried, ALL internet access would be down, or at the very least it'd be completely random outages and not *always* loading some sites and always *not* loading others - but there you go.

(since searching for possible solutions, I found a LOT of people with similar problems, and very few actually posting solutions, hopefully this may help someone else down the line)

Hi and welcome,

Sorry for delay. We have been backlogged.

Good to hear you also solved the problem. Definately odd that a borked NIC would cause intermittant issues like that.
Strange indeed.

Since you seemed to have resolved the issue I'll give you a couple sites you can check out to help you keep safe online.
Looks like you pretty well have the security end of it set up good.
May want to consider installing SP3 which will help patch up more holes.

Take care & surf safe!
I'll have an order of massive trojan attack please with a side order of rootkit and virus dip.
Pre-course order of fresh spyware salad please with a side order of polymorphic dressing.
And to drink...a nice tall glass of adware!

For dessert; can I have a bowl of the freshest worms you have please?.

Never Give Up!
