We can access our IIS website on our server from any external computer (ie over the internet) but not internally from inside our network.
I assume I need to add a WWW A record in the dns records for our internal computers to access the website.
Our active directory is ad.ourwebsite.co.nz
However when I add the www record it wont let me change the FQDN. so I end up with www.ad.ourwebsite.co.nz when I am expecting to somehow set www.ourwebsite.co.nz
How do I amend the A record correctly? Or do I need to create a new zone?
