Restart IIS (IISRESET) on All Servers in the SharePoint Farm using PowerShell
Doing IISReset on Server Farm with Multiple SharePoint servers is a painful process. If you ever need to restart IIS on all servers in the SharePoint farm, Here is a nifty solution to do IISRESET on all SharePoint Servers using PowerShell:
PowerShell Script to Restart IIS on All SharePoint Servers:
Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue
#Get All SharePoint Servers - Except DB and SMTP Servers
$Servers = Get-SPServer | Where {$_.Role -ne "Invalid" }
#Iterate through the list and restart one by one.
foreach ($server in $servers)
{
Write-Host "Restarting IIS on server: $($Server.Name)"
IISRESET $Server.Address
#Optional: Get the Status
Write-Host "IIS status for server $($server):"
IISRESET $server.Address /status
}
Write-host "IIS Restarted on All Servers of the Farm!" -f Green
Make sure, you have “Local Administrator” Permission on all servers you want to reset IIS.
