I am running invoke-command on 50 servers and I need to write multiple files to the local machine. I have tried using a combination of UNC paths out-file and write-output, but cant get it to write the files to the local machine.
$data = Invoke-Command -ComputerName $servers -ScriptBlock {
$Server = $env:COMPUTERNAME
$services = Get-Service | Where-Object { $_.Status -ne "Running" } | Select-Object name
$services | Write-Output "\\local\monitor\Services\$Server.html"
$EventLogs = Get-WinEvent -FilterHashtable #{Logname = 'Application'; Level = 1; StartTime = [datetime]::Now.AddMinutes(-15) }
$EventLogs | Out-File "\\local\monitor\Events\$server.html"
}
Edit:
If I run this on the remote server, It will write the file to the local server
$services | Write-Output "\\local\monitor\Services\file.txt"
However, I get access denied running this - I am running PS as admin. Why Access Denied when running invoke-command, but not directly from remote server?
Invoke-Command -ComputerName $remote -ScriptBlock {
"this is a test" | Out-File -FilePath "\\local\monitor\Services\file.txt" -force
$Error
}
Out-File : Access to the path '\\local\monitor\Services\file.txt' is denied.

Try this...
Invoke-Command -ComputerName $Servers -ScriptBlock {
$Server = $env:COMPUTERNAME
$services = Get-Service |
Where-Object { $PSItem.Status -ne 'Running' } |
Select-Object name |
Out-File -LiteralPath "\\local\monitor\Services\$Server.html" -Append
$EventLogs = Get-WinEvent -FilterHashtable #{
Logname = 'Application'
Level = 1
StartTime = [datetime]::Now.AddMinutes(-15)
} |
Out-File -LiteralPath "\\local\monitor\Events\$server.html" -Append
}

I'm trying to access the service status of the remote server. i wrote this
$ServerList = get-content -Path "c:\users\cont015\Desktop\ServerList.txt"
ForEach ($ServerName in $ServerList)
{
$Status= Get-Service -ComputerName $ServerName | ?{$_.DisplayName -like "SQL Server (*"} | select Status | format-wide
if($st -eq "Running")
{
$SeverName
$Status
}
else
{
}
}
it is showing
$Status= Get-Service -ComputerName $ServerName | ?{$_.DisplayName -li ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Get-Service], InvalidOperationException
+ FullyQualifiedErrorId : System.InvalidOperationException,Microsoft.PowerShell.Commands.GetServiceCommand
in error. i don't know what i am missing. but when i run without if condition if shows proper output.
$ServerList = Get-Content -Path "c:\users\cont015\Desktop\ServerList.txt"
ForEach ($ServerName in $ServerList)
{
$Status= #(
Get-Service -ComputerName $ServerName -DisplayName "SQL Server (*" |
Select-Object -ExpandProperty Status)
if ("Running" -in $Status)
{
[PSCustomObject]#{
Server = $ServerName
Status = $Status
}
}
else
{
}
}
Explanation:
Get-Service docs: -DisplayName
Specifies, as a string array, the display names of services to be retrieved. Wildcards are permitted (used instead of Where-Object as such filtering is always faster).
Array subexpression operator #( ). -
Returns the result of one or more statements as an array. The result is always an array of 0 or more objects (i.e. force Powershell to always return an array when a call returns only one object or even $null)
Used [PSCustomObject]#{} in output instead of a sequence of strings (learn advantages at Everything you wanted to know about PSCustomObject).
I am using powershell to pull basic computer information from all computers on a LAN. These computers are not, and will never be on, a domain. I have had some success in my test runs getting the output for all of the machines to save into the c:\scripts folder on the host machine. I am, however, having to use the Invoke-command for every cmdlet so that I can put the Output destination outside of the {}.
$computers = Get-Content -Path 'c:\scripts\livePCs.txt'
foreach ($computer in $computers) {
$username = '$computer\Administrator'
$password = Get-Content 'C:\scripts\encrypted_password.txt' | ConvertTo-SecureString
$credential = New-Object System.Management.Automation.PSCredential($username, $password)
# Local Mounted Shares Enumeration
Invoke-Command -Computername $computer -Credential $credential {Get-SmbMapping | Format-Table -AutoSize} | Out-File "c:\scripts\ComputerInformation\$computer.mountedshares.ps.txt"
# Local Shares Enumeration
Invoke-Command -Computername $computer -Credential $credential {Get-SmbShare | Format-Table -AutoSize} | Out-File "c:\scripts\ComputerInformation\$computer.localshares.ps.txt"
I would prefer not to have to do this and it becomes problematic when I have to use If/Else statements, where, because I cannot put the destination outside of braces, I get a file cannot be found error (since it is trying to save on the remote host). I tried using a share instead, in the below but now am getting an access to the file path is denied error.
Invoke-Command -Computername $computer -Credential $credential {
$computername = hostname.exe
If ($PSVersionTable.PSVersion -ge '4.0') {
If (([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
Get-WindowsOptionalFeature -Online -FeatureName *Hyper-V* | Format-Table -AutoSize | Out-File -Width 1024 "\\$env:computername\scripts\ComputerInformation\$computername.hyperv.admin.ps.txt"
if (Get-Command Get-VM -ErrorAction SilentlyContinue) {
Get-VM | Format-Table -AutoSize | Out-File -Width 1024 -Append "c:\scripts\ComputerInformation\$computername.hyperv.admin.ps.txt"
Get-VM | Get-VMNetworkAdapter | Format-Table -AutoSize | Out-File -Width 1024 -Append "c:\scripts\ComputerInformation\$computername.hyperv.admin.ps.txt"
} else {
Write-Host -ForegroundColor Yellow " Hyper-V feature not installed on this host"
}
} else {
Write-Host -ForegroundColor Red " You do not have required permissions to complete this task ..."
}
} else {
Write-Host -ForegroundColor Red " This commands requires at least PowerShell 4.0 ... manual inspection is required"
}
How do I run this one a remote machine using Invoke-Command but save the output to the local c:\scripts folder?
If the goal is to give yourself the option to output to multiple files on the calling system, you could use a hash table ($results) inside of your script block to store your results. Then output that table at the end of your script block. Based on those keys/values, you could output to file.
foreach ($computer in $computers) {
$Output = Invoke-Command -Computername $computer -Credential $credential {
$results = #{}
$computername = hostname.exe
If ($PSVersionTable.PSVersion -ge '4.0') {
If (([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
$HyperV = Get-WindowsOptionalFeature -Online -FeatureName *Hyper-V* | Format-Table -AutoSize
if (Get-Command Get-VM -ErrorAction SilentlyContinue) {
$VMInfo = Get-VM | Format-Table -AutoSize
$VMNic = Get-VM | Get-VMNetworkAdapter | Format-Table -AutoSize
} else {
Write-Host -ForegroundColor Yellow " Hyper-V feature not installed on this host"
}
} else {
Write-Host -ForegroundColor Red " You do not have required permissions to complete this task ..."
}
} else {
Write-Host -ForegroundColor Red " This commands requires at least PowerShell 4.0 ... manual inspection is required"
}
$results.Add('HyperV',$HyperV)
$results.Add('VMInfo',$VMInfo)
$results.Add('VMNic',$VMNic)
$results
}
$Output.HyperV | Out-File -Width 1024 "c:\scripts\ComputerInformation\$computer.hyperv.txt"
$Output.VMInfo | Out-File -Width 1024 "c:\scripts\ComputerInformation\$computer.VMInfo.txt"
$Output.VMNic | Out-File -Width 1024 "c:\scripts\ComputerInformation\$computer.VMNic.txt"
}
If the goal is to simply output all data to one location, you can simply store your Invoke-Command result into a variable. Then write the variable contents to file:
$Output = Invoke-Command -Computername $computer -Scriptblock { # my code runs here }
$Output | Out-File "C:\Folder\$computer.txt"
If you are looking to capture Write-Host output in a variable, you will need to send the information stream to the success stream ( { script block } 6>&1 }
You can redirect the output
$YourScriptBlock = { your script }
$result = Invoke-Command -ScriptBlock $YourScriptBlock 4>&1 -Computer $c -Credential $c
Afterwards the contents are in $result
write-output $result
I'm on a Windows server 2008 R2 and I need an extract of the local profile list, so I use Powershell to look into the registry and get what I want :
$path = 'Registry::HKey_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\*'
$items = Get-ItemProperty -path $path
Foreach ($item in $items) {
$objUser = New-Object
System.Security.Principal.SecurityIdentifier($item.PSChildName)
$objName = $objUser.Translate([System.Security.Principal.NTAccount])
$item.PSChildName = $objName.value
}
echo $items | Select-Object -Property PSChildName | Export-Csv
C:\scripts\PSScripts\UserProfile.csv -Encoding UTF8
It worked with another machine using Windows Server 2012 R2 but here I got a lot of errors, but always the same one :
Exception calling "Translate" with "1" argument(s): "Some or all
identity references could not be translated." At
C:\scripts\PSScripts\users_profile.ps1:5 char:34
+ $objName = $objUser.Translate <<<< ([System.Security.Principal.NTAccount])
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
The .csv file is created but with issues, like a profile shown more than one time, like this :
DOMAIN\User1
DOMAIN\User2
DOMAIN\User3
DOMAIN\User3
DOMAIN\User4
DOMAIN\User5
DOMAIN\User5
DOMAIN\User5
DOMAIN\User6
Is there a difference between WS2008 and WS2012 which can cause this problem? Or is it something else?
I'd suggest using WMI to be consistent across platforms plus some error handling:
$path = 'C:\scripts\PSScripts\UserProfile.csv'
Get-CimInstance -ClassName Win32_UserProfile -Filter Special=FALSE -PipelineVariable user |
ForEach-Object -Begin {$ErrorActionPreference = 'Stop'} {
try
{
$id = [System.Security.Principal.SecurityIdentifier]::new($user.SID)
$id.Translate([System.Security.Principal.NTAccount]).Value
}
catch
{
Write-Warning -Message "Failed to translate $($user.SID)! $PSItem"
}
} |
Select-Object -Property #{Label='PSChildName'; Expression={$PSItem}} |
Export-Csv -Path $path -Encoding ascii -NoTypeInformation
PSv2 solution:
Get-WmiObject -Class Win32_UserProfile -Filter Special=FALSE |
ForEach-Object -Begin {$ErrorActionPreference = 'Stop'} {
try
{
$sid = $_.SID
$id = New-Object -TypeName System.Security.Principal.SecurityIdentifier -ArgumentList $sid
$id.Translate([System.Security.Principal.NTAccount]).Value
}
catch
{
Write-Host "Failed to translate $sid! $_" -ForegroundColor Red
}
} |
Select-Object -Property #{Label='PSChildName'; Expression={$_}} |
Export-Csv -Path $path -Encoding ascii -NoTypeInformation
I'm trying to connect a remote server and stop a process on it using this PowerShell command
Invoke-Command -ComputerName \\srvwebui3 -ScriptBlock {
Get-Process | Where-Object {
$_.Path -like "\\abd\net$\abd\versions\Bin\HttpServer.exe"
} | Stop-Process
}
but I got this error message after executing it:
Invoke-Command : One or more computer names is not valid. If you are trying to
pass a Uri, use the -ConnectionUri parameter or pass Uri objects instead of
strings.
At C:\powerShell\stop-process.ps1:4 char:15

+ CategoryInfo : InvalidArgument: (System.String[]:String[]) [Invoke-Command], ArgumentException
+ FullyQualifiedErrorId : PSSessionInvalidComputerName,Microsoft.PowerShell.Commands.InvokeCommandCommand
Here a PowerShell code that worked:
Invoke-Command -ComputerName <computerName> -ScriptBlock {
Get-Process | Where-Object {
$_.Path -like \\bbb\abab$\bs\MainRls\Bin\HttpServer.exe"
} |
Stop-Process -Force
}
In powershell, I would like to kill all processes for all users, except explorer and processes used by the system
This is where I am including the errors that are given:
$Cred = Get-Credential;
Invoke-Command -ComputerName localhost -Credential $Cred -ScriptBlock { Get-Process $env:ALLUSERSPROFILE | Where-Object -FilterScript {$_.Name -ne "SYSTEM, NETWORK SERVICE, LOCAL SERVICE"} | Where-Object -filterscript {$_.Name -ne "explorer"} | Stop-Process -WhatIf }
Cannot find a process with the name "C:\ProgramData". Verify the process name and call the cmdlet again.
+ CategoryInfo : ObjectNotFound: (C:\ProgramData:String) [Get-Process], ProcessCommandException
+ FullyQualifiedErrorId : NoProcessFoundForGivenName,Microsoft.PowerShell.Commands.GetProcessCommand

Here, this should work for you.
Function Stop-UserProcesses{
Param([string]$Computer = "localhost")
$Cred = Get-Credential
Invoke-Command -ComputerName $Computer -Credential $Cred -ScriptBlock {
Get-Process -IncludeUserName | Where{!($_.UserName -match "NT AUTHORITY\\(?:SYSTEM|(?:LOCAL|NETWORK) SERVICE)") -and !($_.ProcessName -eq "explorer")}|Stop-Process -WhatIf
}
}
Once you are convinced that it is functional remove the -WhatIf. Then just call it as Stop-UserProcesses to end everything locally, or Stop-UserProcesses SomeComputer01 to end everything on a remote system (assuming you have remote sessions enabled in your environment).
Edit: Well then, evidently the -IncludeUserName switch is new in v4. So, in order to do what you want we have to jump through hoops and use Get-WMIObject on the win32_process class, then execute the GetOwner() method for each process. Probably want to filter it so we don't end up with things like Idle throwing errors when they don't have an owner, so we'll make sure that the CommandLine property exists.
Function Stop-UserProcesses{
Param([string]$Computer = "localhost")
$Cred = Get-Credential
Invoke-Command -ComputerName $Computer -Credential $Cred -ScriptBlock {
#Get all processes
$Processes = get-wmiobject win32_process|Where{![string]::IsNullOrEmpty($_.commandline)}|Select *,#{l='Owner';e={$_.getowner().user}}
#Filter out System and service processes
$Processes = $Processes | Where { !($_.Owner -match "(?:SYSTEM|(?:LOCAL|NETWORK) SERVICE)") }
#Get processes and filter on the Process ID and name = explorer, then pipe to stop-process
Get-Process | Where { $Processes.ProcessID -contains $_.id -and $_.name -ne "explorer" } | Stop-Process -WhatIf
}
}
