Hi everyone,
We host our website internally. From outside our network, we can see the site fine. However, internally, when navigating to the site, my browser times out. I've flushed the DNS cache on our domain controller as well as running ipconfig /flushdns on a client machine I work from. Still no luck. Currently, a workaround for this was to add the internal server name to the hosts file on the machine. While this works it's an administrative nightmare.
I am curious about what could be causing this issue. I've added a new zone and A record in that zone for our website and put in our internal IP. This also works fine. What I don't understand is why the website cannot resolve by using DNS forwarders we have set up on our DNS server/Domain Controllers. When I navigate to the site from a client machine, the request times out although our external ip is resolved to the hostname (as seen in the Cached Lookups folder on our DC).
Any ideas? I'm thinking maybe it's a firewall issue?
Thanks for your help!
