Starting and stopping Application Pool using Powershell

Hi,

Providing sample powershell script to start and stop Application Pool of an application hosted in IIS.

Save the below script in a file called as IISCmds.ps1
#Start To Start Application Pool

    Function fnStartApplicationPool([string]$appPoolName)
    {
	  import-module WebAdministration
       if((Get-WebAppPoolState $appPoolName).Value -ne 'Started')
       {
	      Start-WebAppPool -Name $appPoolName
       }
    }
    
#End To Start Application Pool

#Start To Stop Application Pool

    Function fnStopApplicationPool([string]$appPoolName)
    {
	  import-module WebAdministration
       if((Get-WebAppPoolState $appPoolName).Value -ne 'Stopped')
       {
	      Stop-WebAppPool -Name $appPoolName
       }
    }
    
#End To Stop Application Pool

*	Caller of IISCmds.ps1 file.
    
	#Start - To Stop Application Pool

	$FTPUser = '$$$$$' #Provide Server User Name
        $FTPPassword = '*******' #Provide Password
        $UserName=$FTPUser
        $Password=$FTPPassword
        $ServerName = 'Server IP Address'
	$appPoolName = 'TestSites'  #Application Pool Name

	$pwd = convertto-securestring $Password -asplaintext -force
        $cred=new-object -typename System.Management.Automation.PSCredential -argumentlist $UserName,$pwd

        invoke-command -computername $ServerName -Credential $cred `
        -ScriptBlock ${function:fnStopApplicationPool} `
        -ArgumentList $appPoolName

	#End - To Stop Application Pool

	#Start - To Start Application Pool

	$FTPUser = '$$$$$' #Provide Server User Name
        $FTPPassword = '*******' #Provide Password
        $UserName=$FTPUser
        $Password=$FTPPassword
        $ServerName = 'Server IP Address'
	$appPoolName = 'TestSites'  #Application Pool Name

		$pwd = convertto-securestring $Password -asplaintext -force
        $cred=new-object -typename System.Management.Automation.PSCredential -argumentlist $UserName,$pwd
