Guys!! I've got a big problem with my internet!!
Here's the little story... I used System Mechanic to improve my internet speed, but after that, some websites didn't load anymore!! Like MSN and Microsoft websites!
I already formatted my PC, but the problem wasn't solved!!!!!!!!
I have a local network here in my house, and the PC that's with the problem is the one that use the internet from the other (that have direct internet conexion)...

I don't use any proxy program or anything else! My internet conexion share was established when Windows was installed!

What can I do????????? :cry: 

Thanks for the help!!

I have a similar problem, I can't load www.bigpockets.com on my PC (other in the house can). The problem persists even after a full format / reinstall.

It's not *your* Internet. Oh well you used lower-case for "internet" so I guess that sort of saves you on that one...

This problem could have something to do with MTU and Blackhole routers. I remember seeing this on a Linksys router the first time I ran into it. You had to change the MTU on something to fix it. Try this article from MS:

I don't think you are telling everything, but see my other reply anyway.

What you mean, you don't think I'm telling everything?

ANYWAY: I was chatting to the OP in PM and I thought of a temp fix for anyone affected. Use and online web proxy for the site that don't work.

Ok, but... I don't use any router... The PCs are conected directly one with the other...

Both of you could try...

* and...

DrTCP

while following the instructions in the Microsoft article that I sent the link earlier. Which is:

http://www.microsoft.com/technet/community/columns/cabl...
-------------------

* If you don't have a router that's fine. A lot of people don't have a router. Or actually, like me, they are using a box (DSL modem/router, etc.) as a transparent bridge and connecting with Windows XP (e.g. PPPoE). Can your main PC, the one doing ICS, get to the site(s) you have trouble with? Try swapping PC's and make the client now the main connecting ICS box. See if that makes any difference.

The setting changes can be done either in a router and/or in Windows XP. The DrTCP can help to do that. Finding the settings directly in the Registry is mentioned in the Microsoft article. You should "File, export" in regedit to save your registry before any changes in case you want to revert back.

** You didn't tell everything, means you didn't tell much. The more details of how things are interconnected the better someone else can help you. Also telling what you've already tried can be golden.

Thanks!! After I format my PC again I'll try the links!

Well... Here's a layout of the internet connection in my house...

Antenna------------->PC with direct connection-------------->My PC, the one with problems

I already tried to shut down all firewalls, formatted my PC lots of times and tested the internet with SP1 and SP2... Nothing else... :(

So what is that antenna? Is that a WiFi or WiMax connection? Or is that Satellite like Direcway? Also what is between PC With Direct Connection and My PC? Is that just a cross-over cable? Or is that a 10/100 Switch Hub?

Before you format... are you able to try any other computer on that same connection where My PC is currently at? Anything would do, borrow someones laptop (even with them still attached to it ;-) for 10-15 minutes and jack into the CAT 5 10/100 connection.

That would at least give you a troubleshooting decision as to where the problem is.

1.) Test laptop works fine but My PC does not - The problem is in My PC.

2.) Test laptop does not work, has the same problems. - The problem is not in My PC but something in PC With Direct Connection.

* You might want to try something like WinsockXpFix which automates the uninstallation and re-installation of TCP/IP (registry keys Winsock and Winsock 2 - http://support.microsoft.com/kb/811259)

also there are so called LSP fixers. These kind of things can get screwed up by anything from Spyware/Adware to Firewall or other Tune up software that mucks with TCP/IP and LSP stuff.

There is also the old standby (less effective than WinsockXpFix, so probably try this first and then WinsockXpFix):

netsh int ip reset reset.log.txt

* Note: I have also seen trouble where I had to turn off Windows Internet Connection Sharing (ICS) on a Broadband Connection, reboot the ICS PC machine, and then re-enable it and reconnect. But that generally only fixes complete failure of the ICS processes like DHCP, DNS, and NAT/Routing that sometimes gets "stupid" on Windows XP.

Big P.S. You could also benefit from something I told someone else elsewhere on here. Get WinPCAP and Ethereal for Windows and capture your packets. You can also try basic network troubleshooting like PING and TRACERT to see if there is a path to the hosts you are trying to get to.

If the main computer is getting to Microsoft.com and MSN.com you'll see in the Ethereal captures the connection from your IP (or hostname) to Port 80 "http" ... you'll see SYN from you, SYN ACK from them, followed by you another ACK, and then then typically the http GET / request you send to them. Followed by all of the "crap" that comes out of MSN.Com. Yuck!!!!!!! Ad.doubleclick dot what?

Actually before the above TCP 3-way handshake there will be DNS request from you to your DNS Server for the "A" or Address record (the IP address) of the web site you are visiting.

Sorry I made you write so much! But I solved the problem!! (I can't believe I did!)

I used the program MindSoft to modify my internet connection (In hope to get the contrary effect of System Mechanic), and it worked!!!

And... I use Radio internet... the antenna is the device that sends and receive the information with the server! :wink:

* I'm glad to hear that. I'll download that myself and check it out. I'm always looking for tools that make fixing these kinds of things easier.

* What will they think of next? Next thing you know they'll be putting broadband over cellular and Wireless Fi's like Hi Fi's over the airwaves.

On the Moon. And I keep wondering why those astronaut apollo guys don't come here anymore?

There in U.S.A. there's no internet via radio??

No worries mate, I'm from Australia. Just kidding. Don't worry I've been joking these last few posts anyway.

If I don't keep my sense of humor with all this techy stuff and all I'd go crazy.

I did try that Mindsoft download. I guess it's good for 14 days until you have to pay for it. I look around at all the stuff it does ... pretty much like Voodoo Magic. For the most part I have no idea what it's really doing behind the curtain. Kind of reminds me of MS Windows ;-) I did do the Internet tweak part. No idea what it did either but I'm guessing it's an automated tweaking of the settings that they have in there manually for Internet adjustments. This probably means that I was right that it was possibly an MTU problem that you were having. Other program probably messed it up somehow.

Another site that has some neat tools, free for MS Windows, is:
