I have a domain I created as mydomain.com internally which is a public domain as well. My web site is www.mydomain.com. I have a DNS entry internally for www pointing to the external IP. Ping inside hits external IP but browser fails. Root domain mydomain.com still resolves internally to inside ip address. I've created a delegation record for www. Fails. Internal DNS for www resolves but browser fails. I've installed IIS and told it to redirect to www. Outside the domain (different location) works. Something with Windows DNS I'm missing. Please advise.
