	$Cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $Username, $Password
				
	# Checking App Pool by name                
        $AppItem = (Invoke-Command $Server -ScriptBlock{param($AppPool) Get-WebAppPoolState | Where-Object {$_.ItemXPath -match "$using:AppPool"} } -ArgumentList $AppPool -Credential $Cred)[0] 
                                 
        If($AppItem -ne $Null)
        {
            try
