I have a SBS 2011 server running. The domain was fine until today. Users started calling to say that they couldn't get to their shared (mapped) drives. After some troubleshooting I discovered that the issue is related to DNS. DNS resolves all outside addresses correctly but can not locate any records for items located in the domain.
*** UnKnown can't find yvhs.local: Non-existent domain
When I tried to open the DNS manager I receive the following error:
The server server-01 could not be contacted. The error was: Access was denied. Would you like to add it anyways?
I then ran DCDiag /q
The host ccde*********-*********-**********23._msdcs.domain.local
not be resolved to an IP address. Check the DNS server, DHCP, s
Got error while checking LDAP and RPC connectivity. Please check
......................... server-01 failed test Connectivity
There is only one server in the domain and it holds all FSMO roles.
I'm unable to get the DNS server to function because it seems to have lost trust with the AD.
Any help would be greatly appreciated.
