Good day experts,
I have a subdomain (a.abc.com) where my primary AD domain is abc.com. I have DHCP setup to provide addresses and both the forward and reverse zones setup in DNS.
The Windows7 or RedHat linux client receives an address from the proper IP scope, however it will not register with DNS.
The Windows DNS server is set to allow Secure and Non Secure updates (we are on a closed network).
The DHCP server scope is set to Enable DNS dynamic updates.
The primary domain (abc.com) DNS registration from DHCP seems to work just fine.
