Hi there,
I have DirectAccess setup with single NIC, behind a firewall. (IP_HTTPS protocol) I got my Windows 10 clients working initially, then decided to work on getting Windows 7 clients going. So I created the necessary certificates, configured the DCA for Windows 7 then went in to the console and checked 'Enable Windows 7 client computers to connect via DirectAccess'. It worked! However, I went back to my Windows 10 client, and it was now just stuck at 'Connecting'.
When I ran the Directaccess troubleshooter, the Certificate test passed, but it could not create either the Infrastructure tunnel or the User tunnel.
If I uncheck enable Windows 7 clients, uncheck certificates, update policies on my clients then it goes back the other way - Windows 10 will connect, Windows 7 will not.
Any help would be appreciated, I have been trying to figure this out for awhile now.
