Cannot Access ONE site from ONE Machine on Network

Unfortunately I've tried that. I've spent a few hours searching and there are several people with this issue unresolved, but with other sites. I've run all kinds of virus scanners and malwarebytes, spybot... I doubt it's a virus since it's a new machine that's had up to date protection installed from the start.

Have you tried manually setting your DNS servers for that one machine to something like the OpenDNS servers? The other side of the coin is that there's a hole in the DNS lookup table for your ISP, but the other systems already have the info cached, so are able to get to the site. If this is the case, it should resolve itself in a few days, whenever your ISP's DNS servers are set to refresh their lookup tables.

Also, if you've installed any programs that tinker with the HOSTS file, check that as well. IIRC, Spybot will install a HOSTS file, but maybe I'm thinking of something else. There are a lot of people out there who have absolutely no clue what the HOSTS file is for, but they don't let that stop them from doing things that will only cause problems down the road. It wouldn't be the Expedia site itself that was blocked, but maybe there's a site along the chain of connections that is.

You must be using two different DNS between these computers. I noticed;

"Tracing route to www.expedia.com [75.126.192.209]

Tracing route to e6238.a.akamaiedge.net [23.210.147.53]"

That's two different IP addresses for the same site, so doubt it's from the same DNS. Easiest is to set your router to use a certain DNS, but it's possible the W7 computer is able to bypass the router DNS for whatever it is set to in the system. Find out what you have the router set to for DNS and then set the W7 to the same internally. You'll find that where your TCP/IP settings are.

Wow. I spent hours reading other posts from people with the same problem - and almost none of them were resolved. I did check the hosts file, but it was clean. However, my Win 7 PC had a static DNS set up. I changed that sucker over to "obtain automatically" and... I can access expedia. On a side note, my neighbor's PC lists a completely different IP from those two when he tracert's expedia.com

Thanks James and Jimmy. You two are awesome.

Akamai is basically a load balancing company. I'm oversimplifying greatly of course, but they're kind of a failover site for when the main servers are at capacity. So it wouldn't necessarily be out of the ordinary for them to be on a completely different network block.

In any event, looks like the OP's issue is resolved, so it's purely academic. Not sure why a new PC would have a static IP set, but I'm sure there was a reason. Maybe not a good reason, but a reason nonetheless.

Yes - I found it weird that the IP was set to auto, but the DNS was static. I certainly never set that. The onnly thing I can think of is possibly Spybot? I downloaded the newest version, which I don't have on my other machines. Otherwise I can't think of a good reason either.

Maybe, if you still have the values that were put in you could try running a search for that IP address and see what comes up. If it was just something Spybot or some other program did, it should turn up pretty quickly, and if it's something else... Well, it might well be the harbinger of something you definitely would want to know about.

You might want to just check that setting once or twice a week for the next month or so if you don't find a simple explanation from searching the IP address. It probably won't change, but if for example it was the handiwork of some of the bundled garbage that PC makers include on systems these days, sooner or later it'll change back to that static value and you'll want to be ready to undo that change and then hunt down whatever program is changing it and expel it from your system with extreme prejudice.

Now that you mention it, I should have copied the IP before changing it. So far, it hasn't changed. I built the unit, so there was no bundled software. But I'll monitor for changes. Thanks again, you rock.
