hi guys,

before goes further out of hand, ought work fine (maybe bit of overkill, bored during first 3 minutes of lunch-break):

function get-aspreport { 	[cmdletbinding()] 	param ( 		[parameter(valuefrompipeline = $true, position = 0)] 		[string[]] 		$computername = $env:computername 	) 	 	begin 	{ 		 	} 	process 	{ 		foreach ($computer in $computername) 		{ 			try 			{ 				$result = get-wmiobject win32_optionalfeature -filter "name = 'iis-asp'" -computername $computer -erroraction 'stop' 				$props = @{ 					server = $computer 					success = $true 					hasasp = $result.installstate -eq 1 				} 				new-object psobject -property $props 			} 			catch 			{ 				$props = @{ 					server = $computer 					success = $false 					hasasp = "error: $($_.exception.message)" 				} 				new-object psobject -property $props 			} 		} 	} 	end 	{ 		 	} }  get-content "c:\temp\servers.txt | get-aspreport

i know, know, bit undercommented , significant room improvement, function works fine me.

this notwithstanding, jrv absolutely right, gautam: try learning powershell basics. is, i'm sure sneak in format c: equivalent answer without noticing.

learn windows powershell in month of lunches is great book started, addresses common issue admins face (not enough time).

cheers,
fred
