PowerShell: Start service and dependent services

Question

I was looking up how to start a service and it's dependent services, and I was reading this site .

It has an example:

get-service lanmanserver | Foreach { start-service $_.name -passthru; start-service $_.DependentServices -passthru}

However, when I run the above cmdlet, I get the error:

Start-Service : Cannot find any service with service name 'System.ServiceProcess.ServiceController'.

Does anybody know why I'm getting this error? Also, I've been using a different way to start a service and it's dependencies:

get-service lanmanserver | select -expand DependentServices | start-service

Any feedback on the workaround?

Thanks!

This start-service $_.DependentServices returns a collection of services and you're passing it to Start-Service as an argument for the Name parameter (default parameterset's 0th position parameter). Try this instead:

... Start-Service -InputObject $_.DependentServices -passthru ...
