Why we need Host Names?

I hope some of you might be having a question in mind why we need a host name.  I will try to explain the purpose.
You have the following website for a user:


You said that each of the represents the following:

  Financial Site
  HR Site
  Research Site

The problem is difficulty in using those urls as there is no meaning associated with it.  A better solution would be:


So this neat and clean approach requires configuring Host Headers for the SharePoint web applications.  The host header configured will get passed in the HTTP header message.  The host header has to be published inside a DNS server to get it resolved to IP and port.

The approach used here can be used across Windows 7 and Windows 2008 machines.  Please note that you can even configure host names with site collections too.

Our Aim

We are trying to create a web application with the following name:

Following are the steps involved:

Step 1: Create the Host Name

Open the hosts file from the following location:

Enter the following line into it and save the file: myapp.server.net
Now the file content looks like:

Step 2: Create Web Application

Open the SharePoint Central Administration and create a new web application. 

Please note to set the following properties:

  Port: 80
  Host Header: myapp.server.net

The properties are highlighted below:

After entering all the details click the Save button.  Wait for the operation to be completed and you can try entering the url in the browser.

Step 3:
Disable Loopback

If you get a prompt for the user and you may face the following issues:
·  There is continuous prompt for the credentials
·  HTTP 401.1 error

This shows that there is a problem with the Loopback configuration.  This case should occur only when we access the application from the server machine.

For fixing the problem we have to disable Loopback value inside registry.

Open Registry Editor (regedit.exe) and locate the following key:


Create a new Key Value of type DWORD inside it and set the value to 1

Step 4: Test the Host Name

Now you can try entering the host name in the browser and you should be able to access the site after entering credentials.

If you can see the site as shown above then you are done with the Host Header configuration.



In this article we have explored how to quickly setup a Host Name for the SharePoint Web Application. In real world scenarios the SharePoint Administrator need to work with the Network Administrators to configure these entries.
