Direct Access not working on Win7

Hi,

I have configured Direct Access on my Windows Server 2012 Essentials, It works great on Windows 8 but I can’t get it working on Windows 7.

The Windows 7 pc has DCA 2.0 installed, and the admin templates are installed and configured on the server.

The DCA on the Win 7 pc gives me the following error“Windows has lost basic connectivity with corporate resources.Please contact your administrator if this problem persists.”

If I connect via PPTP to the server the DCA connects ok.

So my guess is that it might be related to DNS.

Any advice?
