Why won't my internal DNS Host (A) record work right?
Posted on 2011-03-03
I've setup an internal Host (A) record to point to our external webserver. The record is portal.mydomain.com
Internally I can ping this FQDN and it resolves properly to the external IP. Nslookup also reports the internal dns server and points to our external server. When opening a browser internally and typing in the FQDN it says page cannot be displayed. BUT...........
If I'm outside of our network and type it in a browser it DOES bring up the correct page. I did enter in a dns record for this site in our external dns provider.
So the page comes up fine externally but not internally. I've flushed my dns.
Anything else to check?
