  • Open IIS management console
  • Stop Default web site
  • on the IIS folder right click and add web site
    • provide name of the website  e.g. cloud
    • browse to physical path and create web site folder – path can be custom
    • choose IP address for binding
create new site in IIS

  • click on new web site and from Action Panel –> Edit Permissions –> Security –> Edit –> Add –> location –> mark host from a top and in window  “Enter the object names to select” enter: IIS APPPOOL\<App Pool Name> where pool name is then app pool name which you should take note. In my example is: IIS APPPOOL\cloud

[box type=”warning”] NOTE: first part of the line is case sensitive[/box]

  • click Check names –> OK –> assign Allow Modify to new object –> OK –> OK
  • create a file called default.aspx
  • inset below code to file and save file into new web site folder define during web site configuration

<HTML><BODY>This is vCAC  training web site.</BODY></HTML>

  • type web server url into internet browse and you should see welcome page which you have just created
  • Configure new web site as mentioned on the Step 4

Step 9 – Preparing AD based authorization

By default creating containers objects in AD is disabled, before creation we have to enable it:
