Remotely or locally recycle IIS application pool via PowerShell with AppPool Menu
Save the PowerShell as Recycle-AppPool.ps1 and you can call with or without options.
Recycle-AppPool.ps1 -ServerName REMOTESERVER —– (Will run on a server remotely with current logged in creds)
Recycle-AppPool.ps1 -ServerName REMOTESERVER -WithCredentials —– (Will run on a server remotely with different credentials specified)
Recycle-AppPool.ps1 —– (Will run on locally, defaults to localhost with current logged in user)
<#
.SYNOPSIS
Recycles a selected IIS application pool
.DESCRIPTION
Recycle-AppPools.ps1 uses a PS session to connect to a local or remote computer. It pulls down the currently configured application pools and builds a menu.
The end user gets to select from the menu which application pool to restart. The Recycle-AppPools.ps1 then connects back to the PS Session and recycles the selected
application pool.
.PARAMETER ServerNAme
a single computer name or leave off for localhost
.PARAMETER WithCredentials
Use this switch to specifiy credentials other than the current logged in user.
.EXAMPLE
Recycle-AppPool.ps1 -ServerName REMOTESERVER
Will run on a remote server with current logged in creds
.EXAMPLE
Recycle-AppPool.ps1 -ServerName REMOTESERVER -WithCredentials
Will run on a server remotely with different credentials specified during launch
.EXAMPLE
Recycle-AppPool.ps1
Will run on locally. Defaults to localhost with current logged in user
.NOTES
WithCredentials is a switch, it does not accept any credentials. A prompt will appear later.
