DomainRole

Hello,

I understand this script, only one thing I am interested in and not fully understood, that is "domainRole" property. How can I examine this property if I would like to know the meanings of the number, in this case, if I run this script on my laptop it says "Member workstation" that is true because my laptop is WIN7 and entered Domain. Well, I realized that "domainRole"' property has numbers and meaning.. but How can I see both of them....

The script:

##################################################

$strComputer = Read-Host "Enter Computer Name"
 $objWMI = Get-WmiObject -Class win32_ComputerSystem -namespace "root\CIMV2" `
   -computername $strComputer

Write-Host "Computer: $strComputer is a:"
 switch ($objWMI.domainRole)
   {
   0 {Write-Host "Stand alone workstation"}
   1 {Write-Host "Member workstation"}
   2 {Write-Host "Stand alone server"}
   3 {Write-Host "Member server"}
   4 {Write-Host "Back-up domain controller"}
   5 {Write-Host "Primary domain controller"}
   default {Write-Host "The role can not be determined"}
   }

Thanks in advance,
