I am trying to rename a machine and add it to the domain with 1 restart from WORKGROUP (after the machine gets renamed and joined domain). I tried the code below but it's giving me an error:
$bios = (Get-WmiObject Win32_Bios).SerialNumber
$name = $bios
Rename-Computer -NewName "$name"
$domain = "DOMAINNAME"
$username = "USERNAME"
$password = "PASSWORD" | ConvertTo-SecureString -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential($username,$password)
Add-Computer -DomainName $domain -Credential $credential -NewName $name
Read-Host "The computer will restart in 5..."
shutdown /r /t 5
The error I'm receiving is the account already exist. It does join the domain but not the "Renamed" name that I want.
This is how it has to be done.
Rename-Computer -NewName newserver -Force
Add-Computer -DomainName example.ne -Credential $credential -NewName newserver -Options JoinWithNewName
You could better read the full documentation of Add-Computer cmdelt. Get-Help Add-Computer -Online

I am running PowerShell on CentOS 7.x. I converted working individual commands when running within PowerShell via pwsh to a PowerShell script and then it no longer works. Can someone please shed me some light on what I did wrong?
Here's the working individual commands when running within PowerShell via pwsh.
PS /home/user1/Downloads> $userPw = ConvertTo-SecureString -String "user1password" -AsPlainText -Force
PS /home/user1/Downloads> cd
PS /home/user1> $userCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "user1win", $userPw
PS /home/user1> $s = New-PSSession -computerName 192.168.20.143 -credential $userCredential -Authentication Negotiate
PS /home/user1> Copy-Item -Path /home/user1/Downloads/gssntlmssp-0.7.0-1.el7.x86_64.rpm -Destination "C:\users\user1win\Desktop" -ToSession $s
PS /home/user1> exit
Here's the script when I converted to a PowerShell script so I can pass arguments into it. remote-copy.ps
$remoteHost = $args[0]
$username = $args[1]
$pwp = $args[2]
$source = $args[3]
$destination = $args[4]
Write-Host "Remote Host: '$remoteHost'"
Write-Host "Username: '$username'"
Write-Host "Password: '$pwp'"
Write-Host "Source: '$source'"
Write-Host "Destination: '$destination'"
$pw = ConvertTo-SecureString -String $pwp -AsPlainText -Force
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $username, $pw
$s = New-PSSession -computerName $remoteHost -credential $cred -Authentication Negotiate
Copy-Item -Path $source -Destination $destination -ToSession $s
When I run the script, I got the following error.
[user1#rhel7-tm PowerShell]$ pwsh -File ./remote_copy.ps 192.168.20.143 user1win user1password /home/user1/Downloads/vte-0.28.2-10.el7.x86_64.rpm "C:\\users\user1win\Desktop"

I would be greatly appreciate if someone can point me to where I did wrong. Thanks!
It's a false alarm. The script does work. The issue is by default the MaxEnvelopeSizekb in winrm/config is only 500kb. I need to set to a bigger value if I want to send a bigger file. To set MaxEnvelopSizekb to 500mb, you need to open PowerShell on Windows as Administrator and run the following command.
PS C:\WINDOWS\system32> Set-WSManInstance -ResourceUri winrm/config -ValueSet #{MaxEnvelopeSizekb = "500000"}
I am trying to enter a PSSession using -Computername $Server which was previously defined, but I can't seem to get this to work.
I have tried single, double, and no quotes around the variable at all. What am I doing wrong?
$Servers = Import-Csv "C:\Users\username\Desktop\DNS.csv"
$secpass = ConvertTo-SecureString 'mypassword' -AsPlainText -Force
$myCred = New-Object System.Management.Automation.PSCredential("username", $secpass)
foreach ($Object in $Servers) {
$Server = $Object.Name
Enter-PSSession -ComputerName "$Server" -Credential $myCred
sl HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters
Invoke-Command -ScriptBlock {Get-Item -Path HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters}
Exit-PSSession
}
We use enter pssession for creating an interactive session with the remote computer.
In your case, you do not need to have an interaction with the remote system. You just need to fetch the details from the remote systems which are present in the csv file.
So, Instead of this:
foreach($Object in $Servers) {
$Server = $Object.Name
Enter-PSSession -ComputerName "$Server" -Credential $myCred
sl HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters
Invoke-Command -ScriptBlock {Get-Item -Path HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters}
Exit-PSSession
}
Do This:
foreach($Object in $Servers)
{
$Server = $Object.Name
Invoke-Command -ComputerName $Server -ScriptBlock {Get-Item -Path HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters} -Credential $myCred
}
Note: I believe you have enabled PSRemoting and have edited trusted hosts.
The ComputerName param of Invoke-Command will accept an array of servers so you can do away with the foreach loop entirely and simplify your code to:
$Servers = Import-Csv "C:\Users\username\Desktop\DNS.csv" | Select-Object -ExpandProperty Name
$secpass = ConvertTo-SecureString 'mypassword' -AsPlainText -Force
$myCred = New-Object System.Management.Automation.PSCredential("username", $secpass)
Invoke-Command -ComputerName $Servers -ScriptBlock {Get-Item -Path HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters} -Credential $myCred
I have a PowerShell script I am writing to create new users in our domain, as well as email address. The script works when I run it directly on Exchange. However, if I try to do it from my local PC either with Enter-PSSession or Invoke-Command I get the error:
The term 'Get-ADUser' is not recognized as the name of a cmdlet...
Running that same command from the local machine does work. And running that command on the remote machine works, just not if I run the script remotely.
Here is my script:
$cred = Get-Credential
$first_name = Read-Host -Prompt "What is the new user's first name?"
$last_name = Read-Host -Prompt "What is the new user's last name?"
$copy_from = Read-Host -Prompt "Copy from other user (leave blank if not)?"
$password = Read-Host -Prompt "New user's password?"
$ss_password = ConvertTo-SecureString -String $password -AsPlainText -Force
$new_user_name = $last_name.Substring(0,3) + $first_name.Substring(0,2)
$new_user_name = $new_user_name.ToLower()

Write-Host "Copying user from: " $copy_from_user.Name -ForegroundColor Yellow

#Time to copy their group memberships
Get-ADUser -Identity $copy_from -Properties memberof | Select-Object -ExpandProperty memberof | Add-ADGroupMember -Members $new_user_name
}
$pn = $new_user_name + "#INDY"
Set-ADUser -Identity $new_user_name -GivenName $first_name -Surname $last_name -UserPrincipalName $pn
#Now create email
$email_select = Read-Host -Prompt "Select email domain (1. Woodmizer; 2. Lastec; 3. Brightstone)"
if ($email_select -eq 2)
{

}

$domain = "#brightstoneabrasives.com"
}

If you want this script to run on machines that don't have the Active Directory module, you can simply add this to the top of your script to import the cmdlets via session..
$cred = Get-Credential "DOMAIN\adminuser"
$ADsession = New-PSSession -ComputerName DOMAINCONTROLLERNAME -Credential $cred
Import-Module -PSSession $ADsession ActiveDirectory
I also notice you're trying to run Exchange cmdlets..
$exchSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "http://EXCHANGESERVER/PowerShell/" -Authentication Kerberos
Import-PSSession $exchSession
It looks like the ActiveDirectory module is not installed on that machine, you can install the MSFT RSAT tools to get it.
Try the following, It works!! {I tried after giving the Authentication type}
$pass = ConvertTo-SecureString -AsPlainText 'PASSWORD' -Force
$MySecureCreds = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList 'USERNAME',$pass
$s=New-PSSession SERVERNAME -Credential $MySecureCreds -Authentication Credssp
Invoke-Command -Session $s -scriptblock {
Get-CsUser User
}
I've been trying to rename a domain computer with the following script:
$username = "domain\username"
$password = "password"
$ip = ((ipconfig | findstr [0-9].\.)[0]).Split()[-1]
$hostname = (nslookup $ip)[3]
$hostname = $hostname.replace(" ", "")
$hostname = $hostname.split(":")[1]
$hostname = $hostname.split(".")[0].ToLower()
Rename-Computer -NewName $hostname -DomainCredential $username -Restart -Force
It does everything I desire apart from inputting the password which at this point is a manual process. Can someone advise me on how to get it to input from $password into the prompt box so that I can completely automate the process?
Alternatively, if there's a better way to do it in Powershell, I'm open to going another direction.
You can use this code:
$Username = "DomainUserName"
$Password = "PlainPassword" | ConvertTo-SecureString -AsPlainText -Force
$Creds = New-Object System.Management.Automation.PSCredential($Username ,$Password)
Rename-Computer -NewName $newComputerName -ComputerName $OldName -Restart -DomainCredential $Creds
I'm trying to run Invoke-Command with an answer file to the user credentials but I can't seem to get it to finish running. I'm using a local administrator account so nothing on the domain. Here is what I have and the error:
$Username = "$Env:Computername\admin"
$Pass = ConvertTo-SecureString "12345" -AsPlainText -Force
$User = New-Object Management.Automation.PSCredential($UserName, $Pass)
Invoke-Command -ComputerName $Env:Computername -Credential $User -ScriptBlock {
$Path = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System'
$Name = 'DontDisplayLastUserName'
Set-ItemProperty -path $Path -name $Name -value 0
}
And the error:
[computer] Connecting to remote server failed with the following error message : WinRM cannot process the request. The following error occured while using Kerberos authentication: There are curren
tly no logon servers available to service the logon request.
Any help is greatly appreciated.
Working Solution:
$Username = "$Env:Computername\admin"
$Pass = ConvertTo-SecureString "12345" -AsPlainText -Force
$User = New-Object Management.Automation.PSCredential($UserName, $Pass)
Invoke-Command -ComputerName localhost -Credential $User -ScriptBlock {
$Path = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System'
$Name = 'DontDisplayLastUserName'
Set-ItemProperty -path $Path -name $Name -value 0
}
I finally figured out the problem, hit me kind of randomly. The following line needed to be changed.
Before:
Invoke-Command -ComputerName $Env:Computername
After:
Invoke-Command -ComputerName localhost
Without localhost it was looking at it like a remote computer and not allowing it access.
