Help with script on service

Hey all,
I have been playing with powershell for a few weeks now but I need to write
a script that is way beyond my knowledge so far.

I need to change the service "Remote Procedure Call" to log in with local
system account.

Is there an easy way to do this in powershell?
I have a list workstations.txt I can call to run WMI against but I do not
know the command to change the value.
Thanks for any help

To be completely honest with you... what you are asking for AFAICT should be
strait forward... I was actually ready just to post the code, but alas... I
cannot find a method to do what your want with .NET or WMI... Actually that
is not entirely accurate... I found a way to set the value with WMI, but it
does not commit to the actual service just the object. I am sure there is a
way to do it, but I would just use sc.exe and save your self the time.

example or something similar:
$cmd = "sc.exe \\$server config $service obj= `"user`" password=
`"password`""
invoke-expression $cmd

Here is an article to help.

p.s. If anyone else has got this work using native Powershell.. I would love
to know how.

Here is a function that should help (Password can be null for built-in
accounts like LocalSystem and NetworkService)

function Change-ServicePassword{
Param([string]$server,[string]$service,[string]$user,[string]$password)

# Setup for WMI
$class = "Win32_Service"
$method = "change"
$computer = $server
$filter = "Name=`'$service`'"

# Getting Service Via WMI
$MyService = get-WmiObject $class -computer $computer -filter $filter

# Setting Parameters for Change Method
$inparams = $MyService.psbase.GetMethodParameters($method)
$inparams["StartName"] = $user
$inparams["StartPassword"] = $password

# Calling Change Method and Return $results
$result = $MyService.psbase.InvokeMethod($method,$inparams,$null)
$result.ReturnValue
}

Query the Win32_Service class from WMI and use its Change() method.
