Over the weekend my Windows Server 2008R2 installed 10 updates from Windows and now my DNS Forward Lookup Zone for YAJASSI01.local is not functioning. I have tried running DCDiag /test:dns and it give the error that "SERVER failed test Connectivity". I have look at setting in the firewall as it sujested and I even set the firewall to all all Incoming connections and restarted the server with the same errors. This is a single server setup running AD, DNS and DHCP.
AD Domain Services shows now errors but DNS is showing Warning 4521 and Errors 4004 and 4015.
