Machine Password

Text file with list of servers - WindowsServers.txt

Grab the data

$CAITInfo = Get-Content .\CAITWindowsServers.txt | Foreach {get-adcomputer $_ -properties PasswordLastSet}

Filter and display

$CAITInfo | Sort-Object -descending PasswordLastSet | FT -property DNSHostname,PasswordLastSet

Grab Older than 30 days... which means either problem? or machine password not updating..

$CAITInfo | Sort-Object -descending PasswordLastSet|Where { $_.PasswordLastSet -lt (Get-Date).AddDays(-30)} |

FT -property DNSHostname,PasswordLastSet

To force a PC\server to reset machine password to AD (where not a DC)

nltest.exe /sc_change_pwd:lc.local

wonder if I can do that via powershell :)
