I am planning on moving my 2003 domain to a 2012 domain, I need to resolve all the dns issues with my current domain. When i run DCDIAG i get the following error for all of my name servers. I have 3 seperate forests. I use forwarders to forward to all my dns servers. I have no DNS issues as far as i know. When i run dcdiag on any of my DC's i get the following error for everyone of my Name Servers.
DNS server: 20.26.212.204 (server.mydomain.com.)
4 test failures on this DNS server
This is a valid DNS server
Name resolution is funtional. _ldap._tcp SRV record for the forest root domain is registered
Delegation is broken for the domain mydomain.com.mydomain.com. on the DNS server x.x.x.x
[Error details: 9003 (Type: Win32 - Description: DNS name does not exist.)]
The only zones in my dns are the _msdcs.mydomain.com and mydomain.com. I do not understand why it is saying mydomain.com.mydomain.com in the error. I am not sure where else to look to try and resolve this error.
Any help greatly appreciated.
Thanks for your help
