Get All Windows XP Machines in an Active Directory Forest

[アーティクル]
03/18/2014

Support for Windows XP ends on April 8, 2014. Some organizations might not be completely off Windows XP and need a good way to determine the status of those workstations. I combined some PowerShell that I wrote a while back to accomplish this:

Pinging a List of Machines in PowerShell

Get Counts of all Operating Systems in a Forest Per Domain

The purpose of this was to find all Windows XP machines in all domains in the forest and then ping each one to determine if it is online. It only looks at XP machines that have active computer accounts in AD and have changed their computer password within the last 31 days (This happens by default every 30 days). This script can also be used to look for any OS, just search the code for “Windows XP” and specify a new filter.

The script doesn’t take any arguments but you must have RSAT and Excel installed on the machine running the script:

Remote Server Administration Tools (RSAT)

For desktop OS’s download RSAT
For server OS’s use Add-WindowsFeature RSAT-AD-PowerShell. *Note, the script will try to install this feature if it isn’t already installed, but it only works for server OS’s.

The output of the script will display the XP count per domain but the rich data is in the Excel file that gets generated. There is a tab for each Domain in your environment:

Fields

DNSHostName: DNS Name from Active Directory
CN: CN from Active Directory
Name: Name from Active Directory
DistinguishedName: DN from Active Directory
Description: Description from Active Directory
OperationSystem: OS from Active Directory
OperatingSystemVersion: OS Version from Active Directory
NameFromDNS: DNS name from DNS
IPAddressFromDNS: IP retrieved from DNS
PingSuccessPercentage: It was pinged 4 times, this is how many were successful
