Hi,

Thank you all in advance for your assistance.  

I have a domain controller setup that handles my entire internal network's DNS, WINS and internal HTTP processing.  For clarity's sake we'll say the domain controller is DC-1.net.  The DC is set up with DNS forwarders to my ISP's DNS servers so that any address outside my network is properly resolved.  However, I do not have a dedicated connection to the internet (well, I do but it's a dynamic IP and I don't really want  the hassle of setting up and maintaining exchange and external web servers) so my external website and e-mail are hosted by a third party through a domain registration also called DC-1.net.

Everything is working fine; i.e., my internal stuff is working and my external stuff is working when accessed from an external web location but when I try to get to my webmail application or to the external domain from inside my network, I encounter an HTTP 404 error message.  I understand that this is because addresses try to resolve inside my domain because the DNS system does not see a need to forward those for external resolution.

So my question, is there a way for me to forward http://webmail.dc-1.net and http://www.dc-1.net for external DNS resolution? Or have I shot myself in the foot by trying to use the same internal name as an externally hosted site?

Many, many thanks for your assistance.

Warmest regards,
P

Thank you, DrDave242, for your assistance.  The sites themselves did not have static IP addresses as the hosting service determined them dynamically.  I've added a static IP address to the external domain and will try creating the hostnames once the IP has had a chance to propagate across the net.

Again, many thanks for your assistance and I will post back with the results.
