Following a server crash (due to 100% of the hard drive space being used-up), the DNS server component of Windows Small Business Server 2011 Essentials failed to come back up. Other services appear to be OK (Active Directory, etc.). When attempting to bring up the DNS server, the system reports "The server X.local could not be contacted. The error was: Access is Denied. Would you like to add it anyway?" If you attempt that ("add it anyway") the server name does get added as a server under DNS, but it has a red circle with a white horizontal line. The right pane tells me to "Configure a DNS Server" but this option is greyed-out under Actions.
I have run some tests (dcdiag /test:dns) but they return the obvious, that DNS can't contact the server. Yet in testing the server (added as described above) using the Monitoring feature under properties, both the "simple query" and the "recursive query" pass the tests.
The only thing I have tried so far is to remove DNS and then install it again. The result ended-up with things exactly the same.
Any suggestions would be most appreciated.
