You ar enot converting it to secure string and PSCredential will not accept it as proper input. ============================================================================= The problem is, I don’t want to pass a clear text password to my function in order to use Invoke-Sqlcmd. The person the execute the PowerShell script will need to provide the required credentials. Both the -AsPlainText and -Force parameters are required or you’ll receive error messages saying you shouldn’t pass plain text into a secure string. I think if we keep the passwords in the text file (even though its in a secure form) and once the file is in the wrong hands, one can decrypt the password easily by running the command below: When we run the PowerShell script, pop out window will appear. Currently I am attempting to use Invoke-Command to accomplish this. We will offer a choice to continue running the script or command as an administrator or to enter alternate credentials instead. In Windows 10, press Windows+X and then choose PowerShell (Admin) from the Power User menu. I need to run a couple of TSMVE commands on a bunch of servers. # and for later use, export it to a file To check if CredSSP is enabled or not, you can run this command (and default you’ll get the result below the command; you need to run it elevated!). I am trying to execute a scriptblock from within a parent script using a different set of credentials. In this blog post, I’ll show you how to add credential parameters to PowerShell functions. This allows me to pass in a credential object like I’ve been teaching you throughout this post. $Account = “MyDomain\MyAccount” Now that you know how to create credential objects, it’s now time to talk about how we add credential parameters to our PowerShell functions. I didn’t need to create an extra $UserName and $Password variable in this example. To securely cache login credentials, you can use the command line utility cmdkey.exe. You can simply execute Get-Credential, which will result in a username and password prompt. Finally found time to post in here. Being in the tech industry, you’ll never escape the need to support and/or deal with legacy applications. I use it all the time within my code to perform simple SQL insert, update, and delete statements. If it is, it will stop the function from executing. To connect to a remote computer under a specific account and run an interactive shell, use the following command: psexec.exe \\lon-srv01 -u user -p password cmd.exe. Let’s start reaching out into our network with Jenkins and take actions on remote machines. I think its reasonable and a great webpage and am quite tired of programmers like ben. Click Start, click Run, type cmd and press ENTER. That wraps up dealing with cmdlets that don’t support [System.Management.Automation.PSCredential]::Empty, so let’s move on to dealing with cmdlets that don’t even have a -Credential parameter. Srv3 = Get-Credential -Message “Please enter the credentials for Account on SRV3 – form : Domain\Account or IP\Account or Machine\Account” You can also store the credential object in a variable, which allows you to use the credential several times. For an example of that, check out Hodge’s blog post Automating with Jenkins and PowerShell on Windows - Part 2. Invoke-Command -ComputerName srv3 -Credential $Credentials.Srv3 -ScriptBlock { MyCommand} # but you can generate the hash with a runas “AccountthatRunTheScheduledTask” There a few key caveats with this approach: The script that runs and reads the saved credentials, must be run … I have been trying to run a couple of dos commands with in powershell. To run a single command: On the Hyper-V host, open PowerShell as Administrator. I also discuss how to get around common issues when working with legacy cmdlets that don’t support a credential object, but before we get started let’s first talk about PSCredential objects and how to generate them. Instead: Console.exe "%1" use command which starts it as admin. Since I added [System.Management.Automation.PSCredential]::Empty as the default value of the -Credential parameter, I can run the command without credentials as well. If you’re not familiar with a technique called splatting, that’s how I’m passing the rest of the parameters to the Set-RemoteRegistryValue function.

The sample scripts, guides and commands on the website are provided AS IS without warranty of any kind. I use the following method a lot when working with continuous integration and continuous deployment tools such as Jenkins, TeamCity, and Octopus Deploy. If you don’t have proper credential input specified, why execute? For more information about splatting, check out this MSDN article. Miro This section of the blog post is dedicated to helping you solve this problem. 3. In Windows 7 or 8, hit Start, and then type “powershell.” Right-click the result and choose “Run as administrator.” In the PowerShell window, type the following cmdlet (PowerShell’s name for a command), and then hit Enter: However this can be a problem if you want to run this script from inside an powershell-script, which has to be run non-interactively.

Having your domain username and password in a script –, BAD PRACTICE – DEGRADES THE SECURITY OF THE ACCOUNT, $username = “domain\username” Sometimes, you won’t want an interactive method of creating credential objects as I just demonstrated.

The if statement checks the value of the $credential and adds the -Credential parameter to Invoke-Command only if it’s not empty, otherwise it issues the Invoke-Command without the -Credential parameter. You then have to pass the secure string and user name to the System.Management.Automation’s PSCredential method. If we do not provide the password or any credentials Powershell will currently available local credentials to authentication remote system.

This function wraps around the Invoke-Sqlcmd cmdlet and queries a SQL server for all its databases. Run the following command to restart the WinRM service: Restart-Service WinRM; Part 3: Test PowerShell Remoting. DISCLAIMER - I still use an if statement to determine if $credential is empty or not, but the difference is I’m just adding a $credential object to a hash table, instead of repeating the entire block of code that uses Invoke-Command. $cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $password. Change directory to . But before I do that let’s first talk about why you’d want to add a credential parameter to your functions. To run an entire PowerShell session 'As Admin' from an existing PowerShell (non-elevated) session: PS> Start-Process powershell.exe -Verb runAs If you use Invoke-Command to run a script or command on a remote computer, then it will not run elevated even if the local session is. The purpose of the credential parameter is to allow you to run the function and/or cmdlet as a different user, some account other than the one currently running the PowerShell session. $Credentials = New-Object System.Management.Automation.PSCredential $Username,$Password Powershell: Run SQL command using different credentials.
