Hello,
I'm having an interesting problem getting Direct Access up and running. I've setup a DA server on Win 2012 R2 with a single NIC behind an edge device. The DA server is da01.corp.domain.com. When I add corp.domain.com to the list of DNS suffixes under Infrastructure Server Setup, my Windows 8 clients can not connect to the endpoint server. When I remove corp.domain.com from the DNS suffix list, my clients can connect, however they cannot reach any other hosts on corp.domain.com.
Oddly, I can nslookup da01.corp.domain.com, but ping does not resolve the host, even if I hard code the name and IP into the local hosts file.
Any suggestions would be appreciated.
