So with that we can remove ALL routes to 10.x.x.x and then add the ONE, the ONLY static route.
Finally, when it's all done, you can do it again but make the static route persistent.

A friend has a 64 bit Windows 7 desktop computer that had not been used in years. She has no router - just a straight connection between her tower and her modem. I checked it out briefly and told her I'd have to take it home to fully investigate it's problems. When I brought it home and hooked it up to my modem there seemed to be no problems with establishing a solid internet connection with Internet Explorer or Firefox.
Nonetheless I ran all the Windows updates, ran a full Malwarebytes scan, cleaned up her msconfig startup, ran JRT, Adwcleaner, RKill, TDSSKiller and a full MSE scan. Nothing of substance was found, and when I re-checked it's connectivity with my modem, it seemed to be running better than ever. But when I took it back to her place it turned back into a pumpkin, displaying the same symptoms as before. Her home page (Google - on both IE and Firefox) would come up, and she could enter search items, receive suggestions and display results. But she was unable to bring up any pages from the Google results - it would just show a blank page with the little blue circle. While I had her tower at my house I made a shortcut to her Verizon email. At my house it displayed her email instantaneously. At her house we just got the same blank page with the blue circle.
Luckily enough, I also took a Windows 7 laptop with me. My laptop, using her ethernet cable and her modem, connected flawlessly. No blank pages. No 'this page cannot be displayed' msgs.
I have no idea. Her tower connects using my modem, but not hers. That seems to rule out a computer problem. My laptop connects using her cable and modem. That seems to rule out an ISP problem.

Given the clues not much more to add except to try Live OS CDs. When I see this I sometimes boot up one of the newer Live CDs. I mentioned that over a decade ago and it's my not so secret to sniff out more clues. It does not tell you much and it's hard for some to see the value. If a Live CD works fine then it's something software on that HDD.

I have no trouble booting, so what good is a Linux bootable disk? How is any bootable media going to help me with connection problems?
Let me apologize, because I'm apparently dense enough to not understand how your reply has any relevance to my question..
As it stands the clues are not here. Well we could say it's a bum machine since others work but I had hopes we could try one of my old standbys. I guess not so maybe a service call or counter is best.
Bob
I fail to see how booting from any disk sheds any light on a connectivity problem. And what sort of 'clues' are you looking for? How can it be a 'bum machine' when it works perfectly with my modem? How could taking it in to a shop (I assume that's what you mean by 'counter') help since the problem is only evident with her tower and her modem together?
Anybody else? How about another forum to suggest?
It's a shame you don't want to try anything. It's a method I've used for decades.
Bob
Let's say your laptop has AUTO MDX and this machine does not.
Also, what if someone or malware tinkered with the route table. Do you know how to check that? It's pretty advanced and I will not go further unless we have good reason. That is, if a bootable Live CD works.
Finally there are some security suites that could do as you wrote when they expire or the date is too far off. So reveal which suite and check the date and time.
Seems a shame to lose time like this. Booting a Live CD could give us direction or more clues.
Bob
How would a Live CD boot give us any more information than we can obtain via a normal Windows boot or a boot from a Windows 7 CD?
I'm certainly willing to download and burn another bootable media. I just need to know exactly what that will tell us about the connections that we cannot get through a normal or W7 CD boot.
An OS such as Linux will run off the cd/dvd this will rule out any hardware problems and so narrow it down.

I must be even dumber that I'd previously thought....
Her tower boots Windows 7 perfectly. And since the modem it's connected to has zero to do with booting, it boots both with my modem and with hers. The only difference is that it gives me a solid wired internet connection with MY modem. It gives an almost useless internet connection with HER modem.
Booting from a Linux CD will do nothing to have an affect on the connectivity. At least nothing that I can see.
Nonetheless I will burn a Linux Live CD which I will take with me next week when I hook up her new modem. If the new modem makes no difference I will bring her tower back here to my house and we can proceed from there. However, since her tower connects flawlessly with my modem I don't know what good it will do.
It's a stumper of an issue. When this happens to me I whip on my bootable CD/USB to see if more clues are revealed. I know it may not help but let's say folk don't want to try it? That's great news for PC/Tablet/Phone sales. Right?
Look, I understand you don't like all this work. But then why do it?
Bob
the same networking cable between the modem and the laptop on your computer that she's using? It might be a crossover cable instead for use between two NIC's and that may be why it's not working for her.
when you read this about the MDX, you could both use the same exact cable, it be a crossover and her computer not be able to automatically switch it the way she needs to use it, but yours could. You need to try a second or third cable, preferably one known to be a "pass through" between her computer and the modem.
http://en.wikipedia.org/wiki/Ethernet_crossover_cable
When there is no router, the cable modem may LOCK ON TO THE FIRST MACHINE and ignore all others for days or across a cable modem reboot.
Sorry I didn't bring this up before. As that is an ISP choice whether it locks down for a day or just a power cycle, try the usual.
1. Power down the cable modem.
2. Move cable to next PC.
3. Power up the cable modem.
4. Wait for it to sync with the ISP.
5. Boot the PC.
Annoying but how else can their tech support earn their keep?
Bob
that her computer is set to a static IP address which his modem/router at home is willing to DHCP to her computer, but the modem at her house won't, but only will accept what it offers? Be interesting to have a netstat run on her computer when it's plugged in.
That little test could have revealed a lot and set a direction. But they resisted and here we are guessing badly. Guess some like it rough.
Bob
Guessing badly, actually structure your questions in format so you can rule stuff out logically and it isn't called guessing.
Hi,
Firstly a static IP address - Ensure that this is set to DHCP on the computer, if fails you can always set a static IP wtihin the subnet range depending on the router they normal base of a 192.168.x.x which is normally in the 255.255.255.0 subnet giving you any IP address upto 192.168.x.254 which gives you 254 hosts. Just keep the 192.168.x the same and then any number between the last x and 254. It's a bit hard to explain without going into technicality so if you need confirmation on the static IP just supply the default gateway, just need to ensure that DHCP won't pick up the IP address you are using statically which you can configure through the router.
Second of all I would do theortical diagnostics to see where I can find any loopholes.
Pinging the default gateway and ensuring you can actually see the default gateway by ipconfig (ensure its Ethernet Adapter Local Area Connection) or atleast something along those lines.
This will test the cable itself and ensure that from her PC to the Modem its fine.
I do agree with the guys on the live CD theory which would help as it would rule out any potential compatibility issues between the computer/modem. However its not the only way to do this.
Changing the Modem is definitely something I would recommend to ensure.
Thirdly if you are still stumped, we have confirmed no static IP, connectivity to the modem via pinging the default gateway then I would ping IP addresses to ensure no DNS issues occurring on the line. For example, ping 8.8.8.8 and see if you get a response.
Lastly if still having issues I would try and run a tracert to see if we have any routing issues, however I couldn't imagine this as you have tried another computer.
Let me know if you need any further assistance and if you do respond I would like to see all the diagnostics above and advise on how they went. At the moment I can't think of anymore things straight of the top of my head. Its a difficult one that's for sure, but let me know the results and im sure I can think of more things.

However please note the most obvious answer would be a static IP address set up. However this would be a potential possibility if you used a live CD and it worked. (This is why it would be recommended + multiple more things)

I can't thank everybody enough for their input on this, but I continue to be troubled by something I thought I'd made abundantly in the thread title and in the first sentence of my initial post - THIS IS A WIRED CONNECTION. SHE HAS NO ROUTER.
Sorry about shouting everybody, but Aaron's reply, which seems incredibly astute, keeps mentioning the word router, and talks about pinging the default gateway, which is of course the router. In fact everything in his reply seems to be based on the assumption that a router is a part of this equation. It's not.
Maybe you guys are talking computerspeak that is so far over my head that it's not even funny, in which case you have to dumb it down a little.
She should probably get her new modem tomorrow, and if that piece of equipment fixes all her problems, then this discussion is moot. I simply couldn't get my head around her modem not enabling her tower to establish an internet connection, but working with both of my laptops. (Both laptops were using her ethernet cable and her modem). But her tower works perfectly with my modem. That's it. If anybody has suggestions that don't involve a router, please post.
use the same "wire" to connect between her modem and your computer that she uses between them?
Sadly it is not considered computerspeak anymore about the steps I noted at http://forums.cnet.com/7726-7583_102-5584923.html?tag=posts;msg5584923
And that direct connection could be a side effect of Auto MDX which you as a networker would know or bone up on. Not all modems or PCs implement Auto MDX but more and more do to avoid support calls.
Seems a shame to not install a 20 buck router or hub and call it fixed.
Bob
The new modem that I expect to arrive via UPS later today will be a combination modem and router. Hopefully it will fix all....
The answer was my Win Pro 7 has 32 GB of Memory. My Windows XP because of Bus limitations has 8 GB of memory but only sees 2 GB of memory. I was getting Memory timeouts everytime I kept using the Windows XP machine even though it was WIN XP Pro. I ended up upgrading my server and Network to windows 7 Pro. Had to do it for business reasons.
