I hope someone can help with this, it feels like a stupid question but I'm trying to learn in a semi-live environment and I've had trouble finding an answer to this. I'm trying to be specific, so I hope this doesn't just immediately get closed for a reason I don't understand.
I have a Windows 2012 domain. It seemed simple to me to call the domain fishkake.com (not my real FQDN) but I've seen other posts here that say I shouldn't do that. So my domain is called angel.fishkake.com. And I use NETBIOS and UPN as per another SF post so that users should never see the word angel.
In tutorials for DNS (example: https://support.microsoft.com/en-us/help/324260/how-to-configure-dns-records-for-your-web-site-in-windows-server-2003), I've seen how to add a CNAME for www but this is based on a zone called domain.com. My zone is called angel.fishkake.com but I want a CNAME for www.fishkake.com - NOT www.angel.fishkake.com.
The actual problem which started me down this track was that I have a mail server running on platypus.angel.fishkake.com which I want to install a SSL certificate on.
So the question is, how do I remove angel?
Do I need to create a new zone called fishkake.com that mirrors angel.fishkake.com?
Thanks for your help.
