I need to connect to a remote server and do some file copies and moves, etc. The remote server requires authentication.
What UNC path do I need to enter in for PSCredential? Is it the path to a particular remote user like
\SERVER2\Users\Administrator
Or is it the path to the remote resource itself like
\SERVER2\Data\Content
...
Authenticate the call
$Creds = New-Object -Typename System.Management.Automation.PSCredential -Argumentlist "C:\Some\Path",$PW
Copy-Item $src $destination -Credential $Creds
It is the username. Your paths are not proper UNC paths however. They should start with two slashes like \\SERVER2\Users\Administrator
Specify the credentials of the user with permission to access the resource. The Get-Credential commandlet can get the credentials for you.
$cred = Get-Credential
Copy-Item $src $destination -Credential $cred

How does one connect anonymously to an SMB share in powershell using New-PSDrive?
I've tried omitting the -Credential param but this seems to use the currently logged in user. This works when I test using a domain account, however the problem is for normal operation the currently logged in user is a local kiosk user for assigned access that the domain file server does not recognize.
I've also tried using the following, however it prompts for user input. As this is run as a scheduled task for background operation - this is unacceptable.
$Credentials = Get-Credential -UserName 'NTAUTHORITY\Anonymous Logon'
New-PSDrive -ErrorAction Stop -PSProvider "FileSystem" -Root "$RemoteFolder" -Name "$RemoteDriveLetter" -Credential $Credentials -Persist -Scope Global | Out-Null
I have enabled the local security policy option on the file server for "Network access: Let Everyone permissions apply to anonymous users".
How do I utilize the "anonymous" user connection with New-PSDrive?
-- edit --
I've also tried this
$Credentials = [pscredential]::Empty
New-PSDrive -ErrorAction Stop -PSProvider "FileSystem" -Root "$RemoteFolder" -Name "$RemoteDriveLetter" -Credential $Credentials -Persist -Scope Global | Out-Null
However, the output is:
>> TerminatingError(New-PSDrive): "The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: The specified network password is not correct"
The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: The specified network password is not correct
Anonymous mounts use an 'empty' user and password for the credential block so you can do the same.
This works for me and allows file creation on the share:
$User = " " # Create 'empty' username
$PWord = ConvertTo-SecureString -String " " -AsPlainText -Force
$Credentials = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $PWord
New-PSDrive -PSProvider "FileSystem" -Root "$RemoteFolder" -Name "$RemoteDriveLetter" -Credential $Credentials -Persist -Scope Global | Out-Null
I'm building a VM image in Azure through automation pipelines using PowerShell. One of the requirements is to install a certificate on the CurrentUser store for a specific user. When I am currently logged into the VM, I can run the following command through Azure Run Commands:
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $PWord
$session = New-PSSession $env:ComputerName -credential $Credential
$command = {
param($certPassword, $filePath)
Import-PfxCertificate -FilePath $filePath -CertStoreLocation Cert:\CurrentUser\My -Password $certPassword
}
Invoke-Command -ScriptBlock $command -ArgumentList $certPassword,$filePath -Session $session
When I am not currently logged into the VM under that user, I get an Access Denied error. The error goes away as soon as I login to the machine again. If I run the pipeline while I'm logged into the VM, it succeeds.
What is different about PowerShell permissions while I am logged into the VM?
I need to be able to allow users from a remote domain to change their password and I cannot install RSAT tools and the machine they will be working on.
I have tried an Invoke-Command passing domain admin credentials to run some code on a domain controller however I cannot get Invoke-Command to authenticate.
$InvUsername = "admin"
$InvPassword_Text = "adminpassword"
$InvPassword = ConvertTo-SecureString -AsPlainText $InvPassword_Text -Force
$InvCreds = New-Object System.Management.Automation.PSCredential -ArgumentList $InvUsername,$InvPassword
$InvSession = New-PSSession -ComputerName 'DC01.domain.co.uk' -Credential $InvCreds
New-PSSession -ComputerName 'DC01.domain.co.uk' -Credential $InvCreds
New-PSSession : [DC01.domain.co.uk] Connecting to remote server DC01.domain.co.uk failed with the following error message : The user name or password is incorrect.
The password is not incorrect BTW.
Do you need to create a new remote PowerShell session to do it? Are you able to contact one of the domain controllers directly?
You could try using .NET's DirectoryEntry and passing credentials. If you know the distinguishedName of the account:
$user = New-Object System.DirectoryServices.DirectoryEntry("LDAP://CN=user,DC=example,DC=com", $username, $password)
$user.Invoke("SetPassword","NewPassword123")
You may also have to tell it to explicitly connect through the LDAPS (LDAP over SSL) port like this:
$user = New-Object System.DirectoryServices.DirectoryEntry("LDAP://DC01.domain.co.uk:636/CN=user,DC=example,DC=com", $username, $password)
But that also assumes that LDAPS is setup correctly with a certificate your computer trusts.
I have a script block that I'm trying to make it run as a different domain user.
$Username = 'domain\test'
$Password = '1234'
$pass = ConvertTo-SecureString -AsPlainText $Password -Force
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $UserName,$pass
Invoke-Command -ScriptBlock{
write-host "hello"
} -Credential $cred -ComputerName $env:COMPUTERNAME
When I run it I got the following error:
[test-pc] Connecting to remote server test-pc failed with the following error message : The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests.
Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM se
rvice: "winrm quickconfig". For more information, see the about_Remote_Troubleshooting Help topic.
Why the script is trying to authenticate locally and not against the DC ?
Thanks
If you don't actually want to run the script remotely, you can use Start-Process to run Powershell as another user, which will then execute your command/script as that user.
(See powershell command line help for full syntax options and examples)
# Using Get-Credential to illustrate, substitute with your own credential code
$cred = Get-Credential
# Run Command:
Start-Process -FilePath Powershell -Credential $cred -ArgumentList '-Command', 'Write-Host "Hello"'
# Run Script:
Start-Process -FilePath Powershell -Credential $cred -ArgumentList '-File', 'C:\folder\script.ps1'
I am having an issue to connect to the remote server using New-PSDrive. The remote server is Windows-based, and only userA has access to write.
By saying that, the following code throws an "access denied" error:
Access to the path '$remoteServerPath' is denied on line3
Code:
New-PSDrive -Name remote -Root $remoteServerPath -PSProvider FileSystem
$destination = [IO.Path]::Combine('remote:', $fileName)
Copy-Item -Path $source -Destination $destination -Force
Now, I am trying to include credential information, but I get a different error!
The network path was not found on line3
$secpass = ConvertTo-SecureString 'myPassword' -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ('domain\userA', $secpass)
New-PSDrive -Name remote -Root $remoteServerPath-PSProvider FileSystem -Credential $cred
$destination = [IO.Path]::Combine('remote:', $fileName)
Copy-Item -Path $source -Destination $destination -Force
Can anyone please help me out? Powershell Ver. 5
Why are you creating a PSDrive for this task?
& NET USE Z: \\server\path /user:domain\UserA 'PASSWORD'
Copy-Item -Path $Source -Destination 'Z:\' -Force
& NET USE Z: /D
If you have their plaintext password, this should work just fine.
