The intention is to create a folder on a remote computer C drive.
I'm trying to run this:
$stageSvrs | %{
Invoke-Command -ComputerName $_ -ScriptBlock {
$setupFolder = "c:\Support\test1"
Write-Host "Creating Support Folder"
New-Item -Path $setupFolder -type directory -Force
Write-Host "Folder creation complete"
}
}
but I get the following error:
Invoke-Command : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty.
Provide an argument that is not null or empty, and then try the command again.

I'm currently working on a powershell script to stop certain windows services and set its startup type to disabled.
My script works fine for services with status stopped however for services that has dependency service running cannot be stopped. I get bunch of errors. I tried to append -Force switch,it aint working too. What could be wrong.
Below is my script.
# Function defintion
function Shut_Services_Down {
# Services array
$services_to_shut_down = #("spooler", "XblGameSave", "Fax")
# Loop each service in the array
foreach ( $node in $services_to_shut_down ){
Set-Service -Name $node -Status stopped -StartupType Disabled -Force
}
}
# Call the function
Shut_Services_Down
error 1

I have a file with IP address of servers. And script reads adress ($line) by adress, but sometimes can occur address of server that will be down. It is necessary to script steel run till end of IP address. So I used -Erroraction Continue to Set_FTPConnection But script break anyway. How to solve this problem?
foreach ($line in $FTPServer)
{
Start-Transcript -Path $results
Write-Host -Object "ftp url: $line"
Set-FTPConnection -Credentials $FTPCredential -Server $line -Session MySession -UsePassive -ErrorAction Continue
$Session = Get-FTPConnection -Session MySession
$Session>>.\sessions.txt
#Write-Host $Error[0]
if($session.UsePassive -eq "True"){$connect="OK"}
else{$connect="FAIL"}
foreach ($item in (Get-ChildItem .\Upload))
{
#Get-FTPChildItem -Session $Session -Path /htdocs #-Recurse
Write-Host -Object "Uploading $item..."
$Send= Add-FTPItem -Session $Session -Path $FTPPlace -LocalPath .\Upload\$item -Overwrite -ErrorAction Continue #>> .\up.txt #.\Upload\test.txt

Continue is actually the default setting. It means that if a non-terminating error occurs, it will show the error and then should be continuing with the command and rest of the script. You could try SilentlyContinue to see if that helps.
Alternatively you could test if the IP Address is connectable first. If you're using Windows 8/Server 2012 or newer and PowerShell v4+ you could use Test-NetConnection -Port 21 to do this specifically for the FTP port, if not you could use Test-Connection instead (which is a PS equivalent of Ping):
foreach ($line in $FTPServer)
{
Start-Transcript -Path $results
Write-Host -Object "ftp url: $line"
If (Test-Connection $line) {
Set-FTPConnection -Credentials $FTPCredential -Server $line -Session MySession -UsePassive -ErrorAction Continue
$Session = Get-FTPConnection -Session MySession
$Session>>.\sessions.txt
#Write-Host $Error[0]
if($session.UsePassive -eq "True"){$connect="OK"}
else{$connect="FAIL"}
foreach ($item in (Get-ChildItem .\Upload))
{
#Get-FTPChildItem -Session $Session -Path /htdocs #-Recurse
Write-Host -Object "Uploading $item..."
$Send= Add-FTPItem -Session $Session -Path $FTPPlace -LocalPath .\Upload\$item -Overwrite -ErrorAction Continue #>> .\up.txt #.\Upload\test.txt
$item|gm >>.\up.txt
if($Send.Name -eq $item.Name){$Rec="OK"}
else{$Rec="!!!-FAIL-!!!"}
$array = $line, $item, $connect, $Rec
$FailTable=New-Object -TypeName PSObject -Property ([ordered]#{"FTP Server"=$array[0]; "File"=$array[1];"Connected"=$array[2];"Uploaded"=$array[3]})

I'm trying to make a script that changes the quota of a specific directory on a remote server. For that I'm using the following code ($Quota and $chosen_username enter as parameters):
$prefix_path = "C:\Shares\Users\";
$path = $prefix_path + $chosen_username;
if($Quota){
invoke-command -computername $servername {Set-FsrmQuota -path $path -Size $Quota+"GB"}
}
if((invoke-command -computername $servername {Get-FsrmQuota -path $path} | select #{n='QuotaSize'; e={$_.Size / 1gb -as [int]}}).QuotaSize -eq $Quota){
return "Success."
} else {
return "Failed."
}
And it is giving me this error:
Cannot bind argument to parameter 'Path' because it is an empty string.
+ CategoryInfo : InvalidData: (:) [Set-FsrmQuota], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorEmptyStringNotAllowed,Set-FsrmQuota
+ PSComputerName : ServerName
I've done debug and the value of $path is correct.
When using invoke-command on a remote computer, the local variables are unknown for the remote host, so you have to use either:
the using prefix for PS >= 3
invoke-command -computername $servername {Set-FsrmQuota -path $using:path -Size $using:Quota+"GB"}
the argumentlist parameter for PS < 3
invoke-command -computername $servername {Set-FsrmQuota -path $args[0] -Size $args[1]+"GB"} -argumentlist $path,$quota
$commonElementsLocation = ((Get-Location).Path + "\FolderMatchingCommonWords.txt")
if ($commonElementsLocation) {
$result += Start-Job -InitializationScript {
$commonElements = Get-Content -Path $commonElementsLocation
} -ScriptBlock $testScriptBlock -ArgumentList "testing" | Wait-Job | Receive-Job
}
Not sure what I am doing wrong here - probably a stupid mistake, but I put a condition around the Start-Job statement, and powershell still gives the following error:
Get-Content : Cannot bind argument to parameter 'Path' because it is null.

In v3 add $using:

You have already used a variable for a script block once with $testScriptBlock. You could just do that again for -InitializationScript?
$anotherSB = [scriptblock]::create("$commonElements = (Get-Content -Path $commonElementsLocation)")
$result += Start-Job -InitializationScript $anotherSB -ScriptBlock $testScriptBlock -ArgumentList "testing" | Wait-Job | Receive-Job
