Hi experts,<br />

I add a host header to IIS6 on 2003 server. I have A-records set up in DNS. I can see the site from my local network, but when I ping it from the internet (using a different ISP to my local network) I can ping the web site, but not the web site with header. I.e. mysite.com pings fine but myheader.mysite.com doesn't ping. I'm using Dyndns.com to resolve my IP, as it isn't static.

can't ping host header

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
