Really weird internet/LAN problem - Help needed
Does this make any sense to anyone - all suggestions wellcome. . . Out of the blue I got serious problems with my cable connection, which was (then) through a linksys router and static IP's on my home LAN running XP as the OS on the two internet connected PC's.
Does this make any sense to anyone - all suggestions wellcome...
Out of the blue I got serious problems with my cable connection, which was (then) through a linksys router and static IP's on my home LAN running XP as the OS on the two internet connected PC's. So I switched to DHCP and plugged the cable modem directly into my main PC, but the problem stays the same. The cable company guys swear everything is in order in their end and claim that something is blocking traffic on my end. I reverted to a month old backup, switched the cable modem - but still face the same same problem.
The problem is that I cannot reach certain websites. They just refuse to display (with IE6) while most sites work OK. To make it even stranger, I can't even ping some of the sites, whereas others ping just fine, but the sites are not necessarily the same. For example; I cannot ping ntcompatibe, but I can view it alright in IE (sometimes some sideframes don't display though). On the other hand, I can both ping and view yahoo.com. Microsoft.com I can neither ping or view, BBC shows up just perfectly everytime.
I had zonealarm installed when this sh1t started, but it's now uninstalled and every reference to it deleted from the registry. Everything had worked just fine for months before.
Where the h-ll should I look for the problem ? Or, as I tend to believe, how can I find evidence for the cable guys that the problem is not on my end ?

You bet its weird. Not one ping worked yesterday, still I was able to browse most sites.
As mentioned I've tried to flush back to a fresh XP install but that didn't help. Anyhow, now I've seen that the problem is varying (I used to be able to ping some but not all sites) I'm pretty convinced that the cable company is to blame, another thing is how I'll be able to convince them about it.

Not challenging anyone's technological knowledge or anything like that but in reading the thread, I have to raise this question: Have you tested all the basics? Did you...
- Changed the NIC to see if it's a hardware problem?
- Changed routers/modems, wiring media, etc?
- Did you manually config the conn with a different IP?

Yes on all counts, except the wiring. And the wire can't plausibly be the part that excludes only certain sites all the time.

Since you've removed the router from the picture, this isn't going to help, but I work for a membership association and have had reports of website blocking from all over the country.
I've asked each person if they have a cable modem - answer yes. Then I ask if they have a router - answer yes. I tell them to reset the router and try again, and every time it's worked for them. We have about 17 different websites, and they were unable to get to ANY of them with the URL or the IP - but once they reset the router, everything was fine. (different brands of routers, btw) I've been searching for an answer for quite sometime, and the only answer I can come up with is that if the website is trying to open too many connections - the router will block it. However, I have nothing except one popup window that I can figure out is trying to open connections. No JAVA, some java script that is client-side, setting one cookie (no call back required) - no database connection opening, etc.
Cable tells me to call the router people, the router people tell me to call the cable company.....you know how it goes.

Thanks for posting your solution, but this discussion was from about 2 years ago.
Likely the cause of your problem was some cached DNS entries.
