With this simple script, you will be able to get the free space available on the C: drive on a list of remote computers. I’m using WMI to request the remote computers.
You can use two different ways for the remote computer list :

• static text file with one hostname per line
• dynamic way using the get-adcomputer cmdlet

Just comment/uncomment the line of your choice in the script below ($list variable)

The returned value is in GB.

#$list = get-adcomputer -filter * -Properties operatingsystem -SearchBase "OU=MyOU,DC=domain,DC=local" | %{ $_.DNSHostName }
$list = gc C:\temp\hosts.txt

$list | % {
	$hostname = $_
	$hostname
	$value = (Get-WmiObject -ComputerName $hostname -Query "select freespace,caption from Win32_Volume where caption='C:\\'").freespace
	$value / 1Gb
}
