Hi,
I'm trying to setup Direct access on a Windows Server 2012 r2 Standard server. The installation goes ok but the operational status of the DNS is not ok.
Error message: None of the enterprise DNS servers DC2,DC1 used by DirectAccess clients for name resolution are responding. This might affect DirectAccess client connectivity to corporate resources.
Some info:
* Our DCs are Windows Server 2008 r2.
* We use a third party certificate to the domain da.company.com.
* The DNS servers are online and responding. I can ping them from the DA server, I can make a nslookup from tha DA server.
* Server is updated with the latest windows Updates.
* The infrastructure is IPv4 only e.g I have not implemented IPv6.
I have goolged for hours and hours and I have not found anyting that could help.
Any help is much apprechiated!
