Hello-
I recently completed a migration from Windows Server 2008 R2 to Windows Server 2012 R2 Essentials. However, I am receiving the 5781 Netlogon error in my System log and also have none of the subdomains, i.e. dc, domains, gc, pdc,listed under _msdcs.domain.local. This is now the only server on my network. This server's IP address is 192.168.20.6 and DNS is configured to use 192.168.20.6. I have two forwarders configured, to my ISP's DNS servers. I have configured the DNS server to only listen on IPv4, though it made no difference if the IPv6 address was enabled.
1. Restarting Netlogon does not resolve the issue.
2. I ran dcdiag /test:dns with logging and received an error that the CNAME record could not be resolved. See dcdiag-pre.log below.
3. I manually created the missing CNAME record using another DC on another domain as a reference (to make sure I did it right).
4. Ran dcdiag /test:dns with logging again. Though I created the CNAME record, it still is unable to resolve. See dcdiag-post.log below.
5. Checked the server/AD GUID in dssite.msc - NTDS Settings. GUID matches.
Please help! Thanks
