<div>
Settings look find and they can ping the server by name and IP where IIS is located.<br />

</div>


<div>
Are there any HOSTS entries on the machine?
</div>


<div>
OK, and the URL contains the DNS name in fully qualified domain name format? &nbsp;And you also pinged that? &nbsp;How aboout firewall settings?<br />
<br />
Is the IE showing local intranet or trusted site on the bottom line?
</div>


<div>
the url is <a href="http:\\ctldeveloper\ctlreports\reports.application" rel="ugc nofollow">http:\\ctldeveloper\ctlreports\reports.application</a>&nbsp;where ctldeveloper is the servername.
</div>


<div>
You appear to have your slashes the wrong way around is that a type fault?? <br />
<br />
Anyway I was going to suggest that you check your proxy settings. If you are using a proxy server and have not excluded the internal address(es) you will get that error, happens to me all the time!
</div>


<div>
I will look at that also. &nbsp;Yes, typed the slashes wrong.

Hello,<br />
<br />
I have a problem where I have a user browsing to a internal web address and ie is showing an error of DNS Fail. &nbsp;We are able to ping the server that the IIS instance is running on but this message keeps coming up when browsing via URL. &nbsp;Not sure what the problem could be. &nbsp;And, this is not happening to everyone either...<br />
<br />
Thanks in advance for any help.<br />

DNS Fail in IE when browsing to a internal web address

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).

Windows Server 2003

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.
