Function Get-ECSWSUSComputerTarget
    {
    <#
    .SYNOPSIS
    This gets a computer target from the WSUS Database. This object is needed for other commands, but can be used for standalone information.
 
    .DESCRIPTION
    This gets a computer target from the WSUS Database. This object is needed for other commands, but can be used for standalone information.
 
    .PARAMETER ComputerTarget
    This is the naming pattern of the systems you're querying. Don't foget that WSUS stores the FQDN of most systems, so you might want to specificy computername*.
 
    You can also specificy other naming patterns like compu*Name*
 
    .EXAMPLE
    This example gets any computer with wks in the name with a timeout of 100 seconds and uses SQLAuth
    Get-ECSWSUSComputerTarget -ComputerTarget "*wks*"
 
    .EXAMPLE
    This example gets any computer with wks and pc in the name with not timeout and uses passthru auth
    Get-ECSWSUSComputerTarget -ComputerTarget @("*wks*","*pc-*")
