PowerShell script for starting service and calling external script on remote machine.. I have most of the script written where it will start the w3svc service (which is what I need). Then I have added an extra elseif statement which will be used to call an external script for each machine listed in servers.txt. These may be powershell scripts or bat scripts.. All I am looking to do is look at servers.txt pull in the server name and then look at the name/location of the script residing on that server and run that script (on the remote server) with a start or stop command. I then am using a write-output in both operations to log exactly what has been done to a log file. Once I get this start script going then I need to use the same script to create a stop script which will use the same servers.txt to stop the w3svc service and run an external script with a stop argument. I am adding the code that I have already. I have tried to use WMI for this so I can leverage Powershell 3 but am not opposed to something different if it is cleaner. Also if there is anything that needs cleaning up in my current script I would appreciate the input.
