Create Random Password and update AD account

Colin Smith Colin Smith Profile: Colin Smith


Not to long ago I was asked to write a script that would create a random password and change an AD account to use that new password. The requirements were that the password be 3 uppercase letters 2 numbers and 3 lowercase letters. Here is what I did.

#Clear out all variables from last run

$newpassword = $NULL

$loops = 1..3

## Set up Random Generator

$rand = New-Object System.Random

$i = 1

$n = 1

#set up loop to generate each section of $NewPassword

foreach($number in $loops)


if ($i -eq 1)


$part = $NULL

$m = 3

$s = 65

$e = 90


if ($i -eq 2)


$part = $NULL

$m = 2

$s = 48

$e = 57


if ($i -eq 3)


$part = $NULL

$m = 3

$s = 97

$e = 122


$n..$m | foreach { $part = $part + [char]$$s,$e) }

$newpassword = $newpassword + $part

$i = $i + 1

Set-QADUser PNI-GUEST -UserPassword $newpassword
