1. <# 
2. .SYNOPSIS 
3.     This script displays basic performance information for a computer 
4. .DESCRIPTION 
5.     This script calls Get-Counter on a computer to obtain default  
6.     performance counters. These are obtained and displayed. The script 
7.     takes a parameter which is the host name to display.
