We performed a domain rename a couple of months ago from;
So the both the domain name and netbios name have changed. The process went relatively smoothly.
Windows Server 2003 R2 SP2
2 DC's: HG5 & HG6
I've noticed in the System Event Logs on both DC's at the same time in the early hours of the morning, it's generating ID:5774 errors "The dynamic registration of the DNS record, blah 600 IN SRV .... failed".
All the records that it generates (there are 13 everytime), reference the olddomain.com.au and it's all related to the DNS record found under the AD zone, eg _ldap._tcp.gc._msdcs.olddomain.com.au.
I've checked the DNS records and the old domain AD zone has definitely gone, and there are no records relating to the old domain in the new domain AD zone.
I can see that these error messages appear when the server reboots, and even narrowed it down to when you restart the netlogon service.
I've run NETDIAG /test:DNS and right at the top of the test I can see;
[WARNING] The DNS entries for this DC are not registered correctly on DNS server 10.x.x.x. Please wait for 30 minutes for DNS server replication.
And the same message repeats referencing the second DC. The rest of the log shows the same references to the old domain name in Event Viewer. Also, I can see references to the same entries in the c:\windows\system32\config\netlogon.dns file.
I've tried netdiag /fix
Renaming the netlogon.dns and netlogon.dnb files and restarting the server. The same entries come back again. This error is driving me nuts and like to get it resolved. Thanks.
