I'm running Windows 8 RTM.  I use wireless internet. All of my apps are unable to communicate to the internet.

Desktop apps works fine.  I'm able to open the store for updates and installing apps.  I'm at home and don't use any kind of proxy.

Can you try to connect via wired connection? If it works with wired connection, you may try to upgrade the wireless network adapter driver and see if it helps. 

Additionally the issue can be caused by programs such as firewall or antivirus. You may troubleshoot in Clean Boot Mode.

Plugging into Ethernet didn't make a difference.  I tried rebooting as well.

I don't have any anti-virus installed, just the default windows defender.  I haven't changed any firewall settings from their defaults.

This post may help.

Resolutions of Metro Apps issues in Windows 8

Resolution 3: Check the Proxy settings.
Resolution 4: Make sure Apps to run is 1024x768 (i'd recommend 1366x768)
Resolution 5: Try to do fresh installation.

Situation 2: All apps in Windows 8 have issues.
Resolution 1: It could be display issue. Try to install the latest video driver or switch to Microsoft driver if there is one available.
Resolution 2: Check the Event Viewer for any errors. If you see DCOM with Event Id 10010, try to delete the OLE key and reboot. Please refer to this post: Metro apps won't start in Windows 8 preview - viewtopic.php?f=3&t=16400
Resolution 3: It could be the hardware issue, please check device manager for any errors.
Resolution 4: Try to logon different account or local administrator account for a test.
Resolution 6: Do clean boot as mentioned bef

Thanks for all the suggestions.  I tried every single one and nothing.

It's a clean install of windows, no upgrade.  There's no errors or unknown devices in device manager.  I'm using the latest Nvidia display drivers.  No event 10010s in event viewer.  Other accounts have the same issue.  Did a clean boot where I disabled all startup items and all non-Microsoft services.

I haven't changed any firewall settings from their defaults.

Try turning on firewall logging?   <eg>

Alternatively, see what NetMon is showing?   You could also get some clues from ProcMon's Network event class.   If the protocol is HTTP you could also use Fiddler2 but for Metro apps you would need to use Eric Lawrence's EnableLoopbackUtility too.

I've tried disabling windows firewall and it doesn't make a difference.

Interestingly, I was just at a hotel where they had wireless and Ethernet available.  I noticed all my metro apps connected to the internet while I was there, on wireless or wired.

Now I'm back at home and once again, no metro internet access.  Before you go and say my router must be blocking it, I have 3 other computers here running Windows 8, and none of them have this problem at all.

Even more strangeness.  I just tried using Fiddler.  When running it, you have to select which Windows 8 app you will monitor.  For any app that I selected to monitor, all the sudden that app would have internet access.  After closing Fiddler, Metro would loose internet access again.

Finally solved my issue.  I had noticed that everytime I run the command ipconfig /flushdns, I would get this error:  Could not flush the DNS Resolver Cache: Function failed during execution.

Searching for that error lead me to this KB article:  http://support.microsoft.com/kb/919746

I then discovered my DNS Client service was disabled.  After starting it, all Metro apps now have internet access.

Many, many thanks!!!!  Somehow, I luckily found this post.

I was having the exact same issue.

I had disabled the DNS Client on Windows 7 because I was using a large hosts file.

This solution worked perfectly!

Thanks you!

Glad I could be of help.

Didn't solve my problem even though it looks like I was under the same situation!

After the upgrade from Winows 7 Ultimate to Windows 8 Pro my PC had the problem that Apps allowed to use the local network were working fine but the once only allowed to use the internet connection as well as the IE App did not work at all.

I have been searching for two weeks until I found out that:

1. Non working Apps on my PC where the once that only have the right to use the internet connection.
2. The reason was a deactivated DNS Client service.

Thanks, this post gave the solution for my pr

Stephen, I have been killing myself over this issue too for the last week - I turned off dns client when I installed HOSTSMAN (http://www.abelhadigital.com/hostsman) as I always have on non domain machines in the past... I did it a few days before and never put the two together....

Thank you for posting the solution.

Thank you, zillion times!

I can conform this. Without DNS Server, the apps have no internet access.

In my case the DNS Cache service was running fine, but Metro apps were still not resolving DNS.

The solution was to run "netsh winsock reset" using an elevated command prompt, then restart.

Would like to say that I have the same problem with Windows 8.1 Pro on 3 different installs. Have tried all of the MS recommendations.

Have tried sing different DNS servers and ISPs (Paired with phone)

Resetting the winsock worked for me but be sure to check internet options (Proxy) & DNS Client service.

Maybe one of the Windows 10 updates will fix this problem with the winsock stack.
