I wrote the post (Fully configure host header for Web application) 2 months ago in order to facilitate how to use host header for your Web application. Using host header allows you to make more easier using SharePoint for end-user. They just need to use friendly URL instead of remembering port number of URL.

In this post, let me share the PowerShell code I made today. PowerShell has a seduction that makes you love when you are in which.

The PowerShell helps you the following:

• Automatically create new Web Application with Host Header
• Automatically create new Site collection in the Web Application
• Automatically remove and then add new binding IIS Web Server
• Automatically create new Host A record in DNS

Add-PSSnapin Microsoft.SharePoint.PowerShell #Add PowerShell Snap-in for SharePoint

$databaseName = "HomeDb"
$databaseServer = "sharepoint2010spinstance" #Use named-instance

#Configure Managed Account
