On a Windows Server 2008 R2 machine, IIS has already been installed and you want to create an additional website. If necessary, an additional IP Address has been added to the server also.
Use the New-Website PowerShell cmdlet to accomplish this task:
New-Item -type directory -path d:\iis\mikefrobbins
New-Website -Name "mikefrobbins" -Port 80 -IPAddress "192.168.1.222" -PhysicalPath d:\iis\mikefrobbins -ApplicationPool "ASP.NET v4.0"
You can get a list of websites running on the server by using the Get-Website cmdlet or by running Get-ChildItem on the IIS PSDrive:
