Hi,
I'm having a problem on a site using NPS (Radius) for wireless (Windows Server 2012 DC).
Basically what's happening is:
Android, IOS and Widows devices (Phones, Tablets) can connect to Wireless using NPs (they are prompted for user name and password which work fine)
Windows 8 Laptops can also connect using AD Credentials ok - There is a Cert prompt on first connection you click ok and connect successfully.
Windows 7 Laptops cannot connect - we get prompted for credentials and we enter them in and get an error stating that the connection was unsuccessful.
The Wireless connection on the Laptops is being managed by Windows and I have tried it on different Hardware with the same effect. I have copied the settings on the Windows 8 Laptops exactly and matched them to the Windows 7 Laptops again to no
effect.
Does anyone have any ideas why the Windows 8 laptops connect successfully but Windows 7 can't? I suspect it's to do with the Cert prompt I get on the Win 8 laptops but don't get on the Win 7's. I have changed the settings of the Wireless connection to all possible
combinations but still no joy.
Any ideas?
