powershell script to unlock local accounts

Try this:

I found this earlier today, it was written by someone else, or copied by one of them, it's almost identical. After loading the module I can't get the 'enable' to actually enable.

Try..

$Username = "TestUser"
$Computer = "ServerA"
[ADSI]$user = [ADSI] "WinNT://$Computer/$Username"
If ($user.IsAccountLocked -ne $null){
	IF ($user.IsAccountLocked -ne $false) {
		Try {
		$user.IsAccountLocked = $False
		$user.SetInfo()
		"Unlocked the account $Username"
		}
		Catch {
		"Error whle Unlocking the account $Username : $($_.Exception.Message)"
		}
	}
	Else{
	"The account $Username is not locked"
	}
}
Else{
"Unable to find user $Username"
}

Thanks Subsun, I am not sure that is the path I want to go down.
I need to run a script nightly, find locked accounts and unlock them. All of them will be local accounts (not Domain accounts) on a single server.

This is the code I was working on to accomplish it, using the local admin modules from Microsoft:

Get-LocalUser | Where-Object {$_.LockedOut -eq $True} | unlock-LocalUser

I never used this module so I am not sure if it works.. You can also use WMI to do this task..

Here is a sample code which will unlock all locked local accounts in computer..

Get-WmiObject -Class Win32_UserAccount | 
 ?{$_.LocalAccount -eq $True -and $_.Lockout -eq $True}| 
 % {
 $User = $_
 $User.Lockout = $false
 $User.Put()
}

Select allOpen in new window

Get-WmiObject -Class Win32_UserAccount
This pulls every name in the Active Directory.... that's like 10K+

You need to add filter..

Get-WmiObject -Class Win32_UserAccount | 
 ?{$_.LocalAccount -eq $True -and $_.Lockout -eq $True}

Select allOpen in new window

Well, when I run it, with the filter, it chugs for like 10 minutes, till I kill it.
So when I ran the first line alone, I could see it was loading thousands of accounts.

I just tried it and it works for me.. Did you try it on any other server and see if it shows same issue?

That works great! Thank you.
