gc serverlist.txt

you change serverlist.txt to the full path of whatever your input file is.

e.g.  gc c:\somefile.txt

My first thought would be that there are multiple dns entries for the same ip.

However there is one way to verify if we need to change something.

For one of the computers in the list, simply run:
nslookup computername 

Open in new window


from a command prompt and see what ip it returns, whether it matches with the report or not.

No it would not so let me break down the script for you:

1.  We populate an array from your list of computers, then loop through that array:
gc serverlist.txt | % {

Open in new window


2. We assign a variable name of $server to each computer in the array:
$server = $_

Open in new window


3.  We populate a new array name $ips with all the ip addresses returned for the computer name value in the variable $server:
$ips = [System.Net.Dns]::GetHostAddresses($server).IPAddressToString

Open in new window


4: We loop through that array and create the labels and report values based on the current iteration of the loop:
	$ips | % {
		$ip = $_
		$item = New-Object PSObject
		$item | Add-Member -type NoteProperty -Name 'SERVER' -Value $server
		$item | Add-Member -type NoteProperty -Name 'STATE' -Value $compstate
		$item | Add-Member -type NoteProperty -Name 'IPADDRESS' -Value $ip
		$report += $item
		
	}

Open in new window


5. We then export that information to a csv file:

$report | Export-Csv c:\report.csv -NTI

Open in new window


So unless the values returned by the population of the $ips array are not correct, then you should be seeing the correct vales in the report.
