In this article we can explore how to quickly setup a Host Name for the SharePoint Web Application.

Why we need Host Names?

I hope some of you are wondering why we need a host name. I will try to explain the purpose.

You have the following website for a user:

http://servername:67655
http://servername:88813
http://servername:12345

Let us say that each of them represents the following:

  • Financial Site
  • HR Site
  • Research Site

The problem is the difficulty in using those URLs since there is no meaning associated with them. A better solution would be:

http://finance.corp.com
http://hr.corp.com
http://research.corp.com

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

http://myapp.server.net

The following are the steps involved:

Step 1: Create the Host Name

Open the hosts file from the following location:

C:\Windows\System32\drivers\etc

Enter the following line into it and save the file:

127.0.0.1 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.

http://myapp.server.net

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 situation should occur only when we access the application from the server machine.

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

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

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

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.
