I have a VM running Windows Server 2012.And some intended services on it. I want to change a configuration file on this VM machine remotely from my desktop pc. Currently I change this configuration file by mapping the C:
drive of the remote server and then changing the file. Now this blocks me from changing multiple servers as I can't map multiple server c:
simultaneously to same drive. Also, mapping hundreds of drives wouldn't be ideal. The way I am changing the file by mapping drive is:
$password = <password text> | ConvertTo-SecureString -asPlainText -Force
$username = "admin"
$credential = New-Object System.Management.Automation.PSCredential($username,$password)
net use Z: \\$ipAddress\C$ <password> /user:admin type 'z:\Program Files\lalaland\Data\Settings.xml'
(Get-Content 'z:\Program Files\lalaland\Data\Settings.xml') | ForEach-Object { $_ -replace $oldString, $newString } | Set-Content 'z:\Program Files\lalaland\Data\Settings.xml'
type 'z:\Program Files\lalaland\Data\Settings.xml'
net use z: /delete
Therefore I searched for a better option and found this script at https://gallery.technet.microsoft.com/scriptcenter/PowerShell-Replace-String-58fbfa85 but it doesn't work for me.
I am using this script as :
.\Replace-StringInFile.ps1 -ComputerName <RemoteComputerHostName> -TargetPath 'C:\Program Files\lalaland\Data' -Fil
eName Settings.xml -Replace $oldString -ReplaceWith $newString -Credential (Get-Credential)
when I run the command credential window pops up asking for username and password. I enter the username and password that I used for mapping the drive, but it throws the following error:
New-PSSession : [<RemoteHostName>] Connecting to remote server <RemoteHostName> failed with the following error message : The user name or password is incorrect. For more information, see the
about_Remote_Troubleshooting Help topic.
At D:\workspace\Replace-StringInFile.ps1:84 char:14
+ ... $Session = New-PSSession -ComputerName $Computer -Credential $Creden ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [New-PSSession], PSRemotingTransportException
+ FullyQualifiedErrorId : LogonFailure,PSSessionOpenFailed
what I don't understand is when I map the drive with the same credentials it works fine but using the other script, which internally uses New-PSSession
doesn't work.
Any idea ?
I was able to do this using the following cmdlet:
function Edit-RemoteFileStringReplace
{
[cmdletbinding()]
param([Parameter(Mandatory=$true)][ValidateScript({$_ -match [IPAddress]$_ })][string]$Address,
[Parameter(Mandatory=$true)][string]$FilePath,
[Parameter(Mandatory=$true)][string]$Replace,
[Parameter(Mandatory=$true)][string]$ReplaceWith,
[Parameter(Mandatory=$true)][System.Management.Automation.PSCredential]$Credential
)
$DriveLetter=""
$FilePathWithoutDriveLetter=""
$DriveName = $Address.replace('.','x')
$DriveName = "PSDrive_$DriveName"
$DriveLetter = (Get-DriveLetterFromPath -Path $FilePath).Substring(0,1)
$FilePathWithoutDriveLetter = Remove-DriveLetterFromPath -Path $FilePath
$MappedFilePath="$DriveName" + ":$FilePathWithoutDriveLetter"
New-PSDrive -Name $DriveName -PSProvider FileSystem -Root \\$Address\$DriveLetter$ -Credential $Credential -ErrorAction Stop
(Get-Content $MappedFilePath) | ForEach-Object { $_ -replace $Replace, $ReplaceWith } | Set-Content $MappedFilePath
Remove-PSDrive -Name $DriveName
}
