Basic and recurrsive DNS tests fail on SBS 2011
Hi
We have a SBS 2011 server with a problematic DNS server. It causes users to randomly disconnect from the network or Exchange server.
The Internet connection wizard of the SBS does not complete. Error - Unable to configure Exchange. We also don't have access to our router (ISP controlled). We have a trusted certificate linked to Exchange. My guess is , that these are the reasons for the Intenet connection wizard not completing and rectifying/configuring the DNS server.
Wen I run the BASIC and RECURSICE tests from within DNS user interface, both tests fail.
Any help would be appreceated with fixing this DNS service

Aadi369 - I have ran the EMTshooter. All tests performed and completed to connect successfully ending with the correct server domain name: servername.domain.local

Solved the DNS problems.
The main problem was that the DHCP server did not resolve the DNS name.
The DHCP server does not resolve and DNS server name. It was blank.
Removed entries under DNS zones .local and reloaded them.
Removed and re-added _mscdc entries (careful not to delete these)
I was able to track down the problems using a combination of utilities.
DCDIAG /FIX and also ADPREP /FIX
Set login detail and domain detail on DHCP
Flushed DNS, register and restarted NETLOGIN
Ensure DNS ISP forwarders are configured (even swapped them around)
Ensure to wait 15+ minutes
This worked for me. After all these steps the basic and recursive tests started passing

DNS problems were resolved for a day only. Problems started occuring again. I will have to post a new quetsion with new developments re this DNS issue. Please close this question and do not list solutions to the public

Just a few things worth mentioning:
Outlook web access, RAS and Outlook anywhere (rpc over http) and VPN is still working perfectly on the server.
Netstat - indicates that the server is listening as DNS server.
The Fix My Network Wizard always prompts to repair the DNS server indiacating that the DNS server is not listening on the correct IP address. The fix my network wizard finishes with a DNS fixed result but yet it complains about the DNS server when the wizard is run again.
