Is there a simple way to change user passwords? I have a csv of the usernames, and the new passwords but Im not sure how to set the new passwords. I have about 11,500 passwords that need changed...

The first hit when I typed "Powershell change windows password" into Google was this. Did you try that?

You don't need to gently caress around with ADSI if you have a newer Powershell version: http://ss64.com/ps/ad.html

In particular: http://ss64.com/ps/set-adaccountpassword.html

You can also use the System.DirectoryServices stuff if you want (which is the way I've done it when I didn't want to have to install the Active Directory module on every PC running my script or when I wanted to "sketch out" something that was going to be C# eventually).

I've got a script I need assistance with. It's ping but with a timestamp and table formatting:

code:

[CmdletBinding()]
Param (
    [int32]$count = 5,
    
    [Parameter(ValueFromPipeline=$true)]
    [String[]]$computer = "google.com"
)

while ($count -gt 0) {
    $ping = Get-WmiObject Win32_PingStatus -Filter "Address = '$computer'" | Select @{Label="TimeStamp"; Expression={Get-Date}}, 
                                                                                    @{Label="Source"; Expression={ $_.__Server }},
                                                                                    @{Label="Destination"; Expression={ $_.Address }},
                                                                                    IPv4Address,
                                                                                    ResponseTime,
                                                                                    @{Label="Status"; Expression={ if ($_.StatusCode -ne 0) { "Failed" } else {"OK"}}}
    
    # Source,
    if ($count -eq 5) {
        $ping | Select TimeStamp, Destination, IPv4Address, ResponseTime, Status | ft -AutoSize
    } else {
        $ping | Select TimeStamp, Destination, IPv4Address, ResponseTime, Status | ft -AutoSize -HideTableHeaders
    }

    $count--
    Start-Sleep -Seconds 1
}

The problem is the formatting. If you run it, you can see basically works but there's way too much spacing. How can I condense the output lines to look like they're part of the same table? Alternately, is there a way to progressively add rows to an output table (I do want progressive output, instead of building up the whole thing and spitting it out all at once)

That whole book barely even touches on scripting, it's all about using it as a shell just like a badass version of DOS.

I have a lot of luck just googling things like "powershell map network drive". Just get help on each command and you'll be set.

The coolest thing you need to know is about the pipe. |
It takes the output of one command and pipes it to the input of the next. Most of the time it just works right.

Try using Dos commands you already know like ipconfig or arp and then piping them to a utility command like Out-File or Out-Gridview. This instantly gives you some new power.

Eventually you'll want to get away from Dos because those commands aren't compatible in a lot of ways. That's when you'll start researching WMI.

I'm literally only a month or two more experienced than you on powershell, if you have any IT background you'll be leaving me in the dust in no time.

I took a stab at this starting with your code and got something going. Basically, keep sending the output down the pipeline as you go, and have a single Format-Table to read in the pipeline. Also, -AutoSize seems to gather all the input first in order to know how to size the table, so that's no good.

PowerShell code:

[CmdletBinding()]
Param (
    [int32]$count = 5,
    
    [Parameter(ValueFromPipeline=$true)]
    [String[]]$computer = "google.com"
)

function Run-Ping {
    while ($count -gt 0) {
        $ping = Get-WmiObject Win32_PingStatus -Filter "Address = '$computer'" | Select @{Label="TimeStamp"; Expression={Get-Date}}, 
                                                   @{Label="Source"; Expression={ $_.__Server }},
                                                   @{Label="Destination"; Expression={ $_.Address }},
                                                   IPv4Address,
                                                   ResponseTime,
                                                   @{Label="Status"; Expression={ if ($_.StatusCode -ne 0) { "Failed" } else {"OK"}}}
        
        $ping | Select TimeStamp, Destination, IPv4Address, ResponseTime, Status

        $count--
        Start-Sleep -Seconds 1
    }
}

Run-Ping | Format-Table

This gives nice table which updates throughout the process.

pre:

TimeStamp               Destination             IPV4Address                        ResponseTime Status

Or instead of piping to Format-Table, pipe it to Out-Gridview for a lightweight GUI with sort/filter, that also updates as it runs.

OK, I feel stupid. How do you properly move contents of one directory to another? It seems like an extremely simple task but if they both contain same-named directories it turns ugly. Let's have directory structure like:

code:

a\
 aa\
  a1
 a2

b\
 aa\
  b1
 bb\
  b2
 b3

I want to move contents of b\ into a\. So aa\ directories should be merged in the end. I've tried:

code:

Move-Item -path b\* -destination a

Result:
Move-Item : Cannot create a file when that file already exists.

b\ still contains aa\, it's not copied/merged into a\.

Tried

code:

Get-ChildItem -Path b\* -Recurse | Move-Item -Destination a

But it returns the same error and copies b1 to a\, not a\aa\. How to do this properly?

Edit: "copy-item -path b\* -destination a -recurse -force" seems to work fine, just need to delete the source after. Meh.

AreWeDrunkYet: Jul 8, 2006

Is there a way to use invoke-command as a sort of fire and forget mechanism instead of waiting for output. I want to kick off a script on a number of computers that I know will hang then error out on a handful of them, but don't want to deal with the waiting and error handling. The plan is to use something like

code:

invoke-command -computername <computer> -filepath <networkpath\script.ps1>

but invoke-command waits for output and passes errors.

code:

invoke-command -computername <computer> -filepath <networkpath\script.ps1> -session new-pssession

Would this work, or does creating (many) new sessions cause other concerns that I need to know about?

Recluse: Mar 5, 2004; Yeah, I did that.

Having troubles with a script I threw together to get/set a list of files that are not owned by BUILTIN\Administrators. It seems to work fine but takes a loooong time to run (~29 hours) on a file server hosting a lot of files. The script is running from the server host the files, and I know I have at least one issue: the Get-ChildItem seems to run relatively quickly, in about an hour or two, and then the foreach loops seems to take up the rest of the time. This presents a problem because when running this on the large shares as the difference in the results from Get-ChildItem and the actual list of files grows and when the file gets run through the foreach loop, the file may no longer exist, which ends up giving me a lot of false positives. For example, I took the results of this with the noncompliant option (just reports users that are not owned by BUILTIN\Administrators) which was an 89 MB csv file and filtered out everything that did not have a blank owner which left me with 720 results and ran that through Test-Path which left me with only 15 files that still existed. I know I could probably fix this at least by doing a test-path within the foreach loop before grabbing the properties, but I'd really like to find out where exactly the slowness is coming from, and how I can possibly resolve. Anyone have any ideas?

I've stripped it down to what I think are the only relevant portions of the script, I can attach the whole thing if needed:

code:

Function FileList ($folder)
{
	write-host Getting current list of owners for files in: $folder
	$files=Get-ChildItem $folder -recurse
		
	foreach ($file in $files)
	{
		$filetemp = New-Object psobject
		$filetemp | Add-member Noteproperty FullPath -Value $file.FullName
		$filetemp | Add-member Noteproperty DirectoryName -Value $file.DirectoryName
		$filetemp | Add-member Noteproperty FileName -Value $file.Name
		$filetemp | Add-member Noteproperty Owner -Value $file.GetAccessControl().Owner
		$fileperm += @($filetemp)
	}
	return $fileperm 
}

	elseif ($option -eq "noncompliant")
	{
		write-host Showing files where owner is not BUILTIN\Administrators.
		$noncompliant = FileList $folder | where-object {$_.Owner -ne "BUILTIN\Administrators"} 
		#Clear existing file
		if (Test-path .\$folder"_noncompliant.csv") {remove-item .\$folder"_noncompliant.csv"}
		$noncompliant | select-object FullPath,Owner | Export-CSV .\$folder"_noncompliant.csv" -NoTypeInformation
		write-host Noncompliance information written to .\$folder"_noncompliant.csv"
	}

I believe it's the foreach loop in the FileList function because when I hit a folder or file that I don't have rights to, I get an error message when trying to add the owner property and I'd see those pop-up every few hours until it finished whereas the Get-ChildItem should only run once in the beginning.

MJP: Jun 17, 2007; Are you looking at me Senpai?; Grimey Drawer

My current scripting hopeful task: I need to identify if files are still in use so we can delete them. I have the following set up which shows me the last access time:

code:

get-childitem D:\temp -rec select-object FullName, LastAccessTime > accesstime.csv

Problem is I know for a fact that these files are on our netlogon share and are logon scripts. Files that are used every day are showing that their last access time was April 2012.

It looks like in Powershell property terms, LastAccessTime is basically last time a file was modified. Is there anything for last time a file was read, or even opened/touched?

You might have figured this out by now but it's your use of Add-Member. There's a lot of old Powershell v1 advice floating about on the web that has been superseded by much better tools in v2 and v3, this is one. In this case there's some advice here on just how slow Add-Member is and how to make custom objects quicker.

I might not be understanding right (I'm not great with coding jargon) but I think Get-Acl is already one step ahead of you. The object you get as output is just a copy of the ACL, if you make any changes to it then you still need to apply them to a target with Set-Acl (or equivalent) afterwards. For example, to take ownership of a folder:

code:

function Take-Ownership($TargetFolder) {
    $CurrentUser = [Security.Principal.WindowsIdentity]::GetCurrent().Name

    $blankdirAcl = New-Object System.Security.AccessControl.DirectorySecurity
    $blankdirAcl.SetOwner([Security.Principal.NTAccount]"$CurrentUser")
    Set-Acl -Path $TargetFolder -AclObject $blankdirAcl

}

My actual code for this actually uses (Get-Item $TargetFolder).SetAccessControl($blankdirAcl) instead of Set-Acl at the end but I can't remember why, but the effect is the same.

E: Just realised that part doesn't actually use Get-Acl, whoops! I'll see if I can't find the right script I was thinking of.

I need to use the shutdown command to restart a computer group in an AD domain. I was told this can only be achieved with a Powershell ISE script,a language in which I'm completely ignorant. The following code was suggested.

$readinputfile = get-content $inputfile
$readinputfile | ForEach-Object {

$objsystem = get-wmiobject -computername $_ -query "select * from win32_operatingsystem"
$result = $objsystem.shutdown()

if ($result.returnvalue -match "0") {
write-host "$_ - shutdown command completed" -foregroundcolor green
}
else {
write-host "$_ - unable to send shutdown command" -foregroundcolor red
}

# ---------- SCRIPT ENDSS HERE------------

Can anyone please explain it a bit for me, and tell me where to add the computer group in question?

Thank you very very much!

I need to use the shutdown command to restart a computer group in an AD domain. I was told this can only be achieved with a Powershell ISE script,a language in which I'm completely ignorant. The following code was suggested.

It's reading a list of computers from an input file, then iterating over every line in the file and shutting it down. You run the script with a command line argument giving the path to the file.

So the command should be "shutdown_script comp_group.txt"?

There's nothing wrong with the code you were given, but here's some code that I've written that's a little more beginner friendly.

code:

Get-Content c:\Servers.txt | ForEach-Object {
Restart-Computer -ComputerName $_
}

This has a lot of weaknesses compared to the code you posted. You have to update servers.txt and you have to copy paste all this directly into powershell instead of running it as a convenient script.

The plus side is that every command in it is well documented and easy to understand, compared to goofing around with WMI.
Get-Content grabs all the servers in c:\servers.txt
the pipe: " | " sends that list to the next command "ForEach-Object"
For each of those servers it tries to execute the command "Restart-Computer" with the argument -Computername $_ ($_ is a special character that represents the current object being manipulated by ForEach-Object)

There's no error detection so you should probably go with your other script for actual work.

Has anyone tried out the idempotent Desired State Configuration stuff in PS 4.0 yet? If the given types do enough things, it seems like a really plausible alternative to Puppet/Chef/SCCM for Windows systems management.

I need to run the script as a task at midnight, so as not to restart everyone's computer in the middle of the day, so I'll try the other script. Thanks anyway!

That's probably a much better idea, I just wanted to show you a simpler idea so you can get an idea of how it all works together.

I'm thinking that you could get the scrip working even better by running the commands as jobs, that way it'll send everything out simultaneously instead of one at a time.

You should be using some variant of Get-ADComputer -SearchBase to find the computers rather than relying on an input file, otherwise you'll have to update the file with machine names every time one gets added.

I've been trying to get those AD commands to work for quite a while. I'm pretty sure that the problem is that Server 2008 SP2 isn't the same thing as Server 2008 R2.

I've got to get some upgrades in this place.

If you're on Win 7, download this then enable the Active Directory Module for Powershell Feature. It's under the Remote Server Admin Tool feature somewhere.

Then either open powershell through the admin tools menu, using the shortcut that includes active directory, or open powershell and do an Import-Module Activedirectory

Edit: Oh, you can also avoid this altogether by just remoting out: Enter-PSSession -ComputerName hostname �credential domain\AD_admin
