Powershell (Version 2.0) remote execution of services with credentials - powershell

Question

I want to start/stop apache and mysql services on remote machine by using powershell version 2.0 (Windows Server 2008). I found syntax for remote execution as follow:
(Get-WmiObject -Computer myCompName Win32_Service -Filter "Name='myServiceName'").InvokeMethod("Stop-Service",$null)
But I have to provide credentials (DOMAIN_NAME\USERNANE and PASSWORD) also for this exceution. I am new to powershell and need help for correct syntax (example will be easy to understand and implement).

Answer 1

Get-WMIObject accepts the -Credential parameter. You shouldn't be keeping your credentials in plain text in your script, so you'll want to prompt for them.
$creds = get-credential;
(Get-WmiObject -Computer myCompName Win32_Service -Filter "Name='myServiceName'" -credential $creds).InvokeMethod("Stop-Service",$null)
If you have PSRemoting enabled on the remote system, you can do this without WMI.
$creds = get-credential;
Invoke-Command -computername myCompName -credential $creds -scriptblock {(get-service -name myServiceName).Stop()};
Update based on comments
Since you're running this as a scheduled job, you should not be storing or prompting for credentials at all. Configured the scheduled job itself (via Scheduled Tasks) to run under the required user account, then either of the following should work:
# Your original code
(Get-WmiObject -Computer myCompName Win32_Service -Filter "Name='myServiceName'").InvokeMethod("Stop-Service",$null)
# If you have remoting enabled
Invoke-Command -computername myCompName -scriptblock {(get-service -name myServiceName).Stop()};
