Powershell v2 script need some help

I think it's the conversion of your password to a SecureString that's doing it. I was able to get your script to work by changing line 2 to this:

$password = type H:\Powershell\MyPassword.txt | ConvertTo-SecureString -AsPlainText -Force 

By default ConvertTo-SecureString takes an encrypted string as its input. -AsPlainText tells it to use a plain text string.

Then there's the idea that you're storing a password in a text file....

$computername = Get-Content H:\computers\Computers.txt; $password = type H:\Powershell\MyPassword.txt | ConvertTo-SecureString $cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist “domain\user”,$password $filename = "{0:yyyy-MM-dd} start" -f (Get-Date) $tid = Get-Date -f HH:mm:ss function StartIfStopped([string]$ServiceName) { $Service = Get-WmiObject Win32_Service -computername $computername -cred $cred -Filter "name='$ServiceName'" if (!$Service) { # Service is not installed Write-Host "$ServiceName is not installed on $computername." } else { # Service is installed if ($Service.State -eq "Stopped") { if ($Service.StartMode -eq "Disabled") { Write-Host "Cannot start service $ServiceName as it is disabled." } else { #Write-Host "Starting service $ServiceName ..." Write-Output "$tid Starting $ServiceName ." >> H:\logfiler\$filename.txt #virker kun lokalt på servere #Start-Service $ServiceName #virker på remote servere også i andre domainer (Get-WmiObject Win32_Service -filter "name='$ServiceName'" -computername $computername -cred $cred ).StartService() } } else { #Write-Host "$ServiceName is already running." Write-Output "$tid already running $ServiceName." >> H:\logfiler\$filename.txt } } } StartIfStopped 'BTSSvc$BizTalkServerApplication' StartIfStopped 'BTSSvc$TASMSMQHost' StartIfStopped 'BTSSvc$TASProcessingHost' StartIfStopped 'BTSSvc$TASSendHost' StartIfStopped 'BTSSvc$TASTrackingHost' StartIfStopped 'BRNTService' StartIfStopped 'TimerService' StartIfStopped 'BouncedMailTracker' StartIfStopped 'CMToolService' StartIfStopped 'CalculationExcelService' StartIfStopped 'ControlNTService' StartIfStopped 'EnvelopeService' StartIfStopped 'PrinterService' 

Update on the script, i got it working but now i need it to log-on multiple servers and start the services.

I know this question is 6 years old by now but anyway.

Looking at the error message. The problem is the $ in BTSSvc$BizTalkServerApplication and all the other service names with a $. It has to be escaped like so:

Get-WmiObject -ClassName Win32_Service -Filter "Name='BTSSvc`$BizTalkServerApplication'"
