Some programs cannot connect to internet

[Jeordie]

AIM works fine and the IM chat program in Steam works fine, but the browser for Steam does not, nor does Windows Live Messenger, Yahoo Messenger, Internet Explorer, or Lord of the Rings Online. Many other programs claim they cannot connect to the internet, such as Lavasoft Ad-Aware when it checks for updates, etc. I use Opera to get online, which works fine. My computer with Windows 7 is connected straight to my 2-Wire modem via ethernet cable, and my laptop with Vista which is connected wirelessly has absolutely no internet issues whatsoever.

I've turned off my firewall, I've checked the exceptions list, I've uninstalled my antivirus, I've turned off Windows Defender, I've checked my LAN settings, I've checked my modem, I've reset the winsock, I've reset the TCP/IP, I've gone through my services in the Windows Management: I've done pretty much everything I know of and nothing works.

Please help!

Run several Antivirus scans - and scan with Malwarebytes.org

I tried that with no luck. I found a couple things that I'm sure my computer is grateful for having removed, but said programs still won't connect.

check your that your dns server ip address is correct from command prompt:

ipconfig /all

It should be the same as your router's configuration page ip address or at least something you recognize (i.e. a real dns server). If not, make it so.

And I'm guessing this part may be your actual problem: In internet explorer, make sure that tools | internet options | connections | lan settings

that there is nothing checked. If there is for any, remove it/them.

Oh wow. I can't believe that was so simple. Unchecking stuff in the LAN settings completely did the trick. Thank you so much, Torrentg! You have no idea
