PowerShell script to modify local account password on multiple remote computers
I had a need to do this for a client.
Problem: Need to change a single user’s account password and flags across multiple systems
Solution:
You can use this script to modify a local user’s password across multiple machines. It will check that the machine is reachable (by ping) and it will set the account to never expire and enabled (userflag 66048)
Modify the $user and $password fields with their desired strings and update the $computers path to the computers.txt file with a list of computers
Run the PowerShell script as someone who is administrator on the machines in the computers.txt file
$computers = Get-Content -path C:\temp\computers.txt
$user = "USER"
$password = "PASSWORD"
Foreach ($computer in $computers)
{
#Start-Sleep 1
$ErrorMessage = ""
$FailedItem = ""
$localuser = ""
if (Test-Connection $computer -ErrorAction stop -count 3 -Quiet)
{
try
{
$localuser = [adsi]"WinNT://$computer/$user,user"
if ($localuser.Path -ne $null)
{
$localuser.SetPassword($Password)
$localuser.userflags = 66048
$localuser.SetInfo()
Write-Host "Password changed on: $computer" -ForegroundColor Green
}
else
{
Write-Host "$user not found on: $computer" -ForegroundColor Red
}
}
catch
{
Write-Host "Error changing password on: $computer" -ForegroundColor Red
#$ErrorMessage = $_.Exception.Message
#$FailedItem = $_.Exception.ItemName
#Write-Host $ErrorMessage -ForegroundColor Gray
#Write-Host $FailedItem -ForegroundColor Gray
}
}
else
{
Write-Host "Unable to connect, not changing password on: $computer" -ForegroundColor Red
}
}
