2. .SYNOPSIS 
3.     This script shows the DNS Configuration  of NICs  
4.     in your system 
5. .DESCRIPTION 
6.     This script is a re-write of an MSDN Sample  
7.     using PowerShell./ The script gets all network 
8.     active network interfaces then prints out that 
9.     interfaces' DNS Properties.

Show-NetworkInterfaces2.ps1

1. <# 
2. .SYNOPSIS 
3.     This script, shows details about the Network Interfaces 
4.     on a system. This is a re-write of an MSDN script into 
5.     PowerShell 
6. .DESCRIPTION 
7.     This script Uses several .NET classes to get the details 
8.     of the interfaces on the system, then displays these details. 
9.     Note in the MSDN Script, there were calls to other MSDN Samples.  
10.     To make things simple, I have removed these calls.
