Sometimes when you make big changes in SharePoint, you would like to do an IISRESET on all the SharePoint Servers, an easy way to do that is by using a PowerShell script.

Instructions:

• Copy code into a text file and save as IISRESET_All.ps1
• Run the script with your SharePoint install account, or any farmaccount
  that has local admin access to the SharePoint Servers.
