Perform an IISRESET on multiple servers using PowerShell

This is quite a quick script, but very useful if you need to restart IIS on multiple servers in one hit. The only pre-requisite is to ensure you have local administrator permissions on each server to perform the IISRESET.

#Specify servers in an array variable
[array]$servers = "Server1","Server2","Server3","Server4"
#Step through each server in the array and perform an IISRESET
#Also show IIS service status after the reset has completed
foreach ($server in $servers)
{
    Write-Host "Restarting IIS on server $server..."
    IISRESET $server /noforce
    Write-Host "IIS status for server $server"
    IISRESET $server /status
}
Write-Host IIS has been restarted on all servers

To use the script, simply replace the server names with those from your SharePoint farm and run on one of the servers.

The script will also output the status of all IIS related services from each server using the IISRESET /status switch.
