When running this simple script I am receiving the error message:
+ CategoryInfo : OpenError: (:) [Import-Csv], UnauthorizedAccessException
+ FullyQualifiedErrorId : FileOpenFailure,Microsoft.PowerShell.Commands.ImportCsvCommand
Param(
[string]$Path,
[string]$Credential
)
Invoke-Command –cn DC –Credential $Credential -ArgumentList $Path –ScriptBlock `
{import-csv -Path $args[0] | select-object –property `
#{name='Identity';expression={$_.username}},#{name='Fax';expression={$_.'fax number'}} `
| foreach{Set-ADUser -Identity $_.identity -Fax $_.fax -Confirm:$false}}
Any idea why this may be happening? I have correct permissions the the path that I am using.
I found the issue and it was because I was not including the CSV file in my path. I was pointing to C:\Files\CSV instead of C:\Files\CSV\fax-users.csv.

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 am trying to update the definition of SCEP on remote Windows Servers using MpCmdRun.exe which exists under "C:\ProgramData\Microsoft\Windows Defender\platform\*\MpCmdRun.exe. Unfortunately it is not accepting -filepath. says its null or empty. below is my code
$comp = "SRV1234"
$MpCmdRun = invoke-Command -ComputerName $comp -ScriptBlock {get-item -Path "C:\ProgramData\Microsoft\Windows Defender\platform\\*\MpCmdRun.exe" | Sort-Object -Property LastWriteTime -Descending |Select-Object -ExpandProperty fullname -First 1}

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

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
When I configure a restricted PowerShell Session like so:
New-PSSessionConfigurationFile -Path c:\PSScripts\test.pssc `
-Description 'Delegation EndPoint Repro' `
-ExecutionPolicy Restricted `
-SessionType RestrictedRemoteServer `
-LanguageMode FullLanguage
Register-PSSessionConfiguration -Path 'c:\PSScripts\test.pssc' `
-Name TestSession `
-ShowSecurityDescriptorUI `
-AccessMode Remote `
-Force
Since the session is of type RestrictiedRemoteServer, I expect the Select-Object Cmdlet be available to end-users. Indeed, when users connect to this session and issue a Get-Command, Select-Object is returned as on of the available Cmdlets.
However when Select-Object is used (for example with -Last parameter), the following exception is thrown.
[localhost]: PS> Get-Command | Select-Object -Last 1
A parameter cannot be found that matches parameter name 'Last'.

What am I missing?
I need to create a script that clears the Lync cache on remote machines. To do so I need to close Outlook and Lync if they are open, and then clear out two folders whilst deleting another. Here is what I have so far:
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') | Out-Null
$computer = [Microsoft.VisualBasic.Interaction]::InputBox("Which computer do you wish to clear the Lync cache for?", "Computer", "$env:computername")
$username = Get-WMIObject -class Win32_ComputerSystem -ComputerName $computer | select username
$RSA = "C$\Users\$username\AppData\Roaming\Microsoft\Crypto\RSA"
$Tracing = "C$\Users\$username\AppData\Local\Microsoft\Office\15.0\Lync\Tracing"
$SIP = "C$\Users\$username\AppData\Local\Microsoft\Office\15.0\Lync"
(Get-WmiObject Win32_Process -ComputerName $computer | ?{ $_.ProcessName -match "Outlook" }).Terminate()
(Get-WmiObject Win32_Process -ComputerName $computer | ?{ $_.ProcessName -match "Lync" }).Terminate()
(Get-WmiObject Win32_Process -ComputerName $computer | ?{ $_.ProcessName -match "Communicator" }).Terminate()
start-sleep -s 3
Get-ChildItem -path \\$computer\$RSA -include * | Remove-Item -recurse -force
Get-ChildItem -path \\$computer\$Tracing -include * | Remove-Item -recurse
Remove-Item -path \\$computer\$SIP\*sip* -recurse -force
The script closes the programs as required, but it doesn't appear to do anything with the folders. The only errors I get are below:

ISE is open as admin. I have admin rights to the domain as well as the folders in question. Can anyone see where I'm going wrong?
