In the Release Preview of Windows 8, when I connect to the internet via wireless and then connect to a VPN or another connection, Metro apps (like Messaging or Sports) complain that the wireless is offline.

How can I fix this problem?

What is the VPN software? – Ciaran Jun 9 '12 at 23:17

Here is a link to the known issues with Cisco VPN's at this time and Windows 8. It could very well be a split dns issue but I am not a network guru by any stretch of the imagination.

If is right, it would seem that a few registry changes could be in order as well as a relatively big change on the server side of things.

You'll need a web server set up on the network your VPN is connecting to which can host a file called ncsi.txt

You'll then need to change registry settings under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet

If you can't do the above, you'll need to get the URLs under the above registry key unblocked by the VPN, presuming is right.

Please can you reword the question and provide some detail as to what the actual problem is - it becomes difficult to help diagnose a problem when we aren't given any information to work with. Also please bare in mind, Windows 8 is still in Beta (or RC I believe) so there will be bugs etc in my opinion to begin with. Why have you made this your main OS anyway?

Windows will try to access a URL to determine network connectivity. Your VPN probably blocked that page.

If your VPN is for accessing a company network, you can disable the default route for that VPN. It's in the connection's properties, networking, TCP/IPv4, advanced, use default gateway ...

If you need the VPN for encryption/privacy, you'll probably have to contact the provider or manually setup a route to provide direct access to that page.

Can you give me a citation for Windows accessing a URL to check for connectivity? Edit: good link right on our doorstep: – Ciaran Jun 9 '12 at 23:09
