Vista - Change Service Account Passwords

Is there a way to change a service account password using PowerShell? I have
a VB Script that will do it, but it's a bit clunky. Thanks!

well, show the vb code and we will translate to powershell for you ...in
shorter forms

I'm not sure translating line by line is the best method - I wasn't sure if
there was a more direct route. At any rate, here's the VB code:
Set oArgs = WScript.Arguments


' Verify the inputs.

If oArgs.Count <> 5 Then
WScript.Echo "Usage: ChangeSQLServiceAccounts.vbs MachineName
InstaNcename ServiceType SQLAccount SQLPassword"
WScript.Echo "ServiceType = 1 (SQLServer), 2 (Agent), 3
(FTE), 4 (DTS), 5 (AS), 6 (RS), 7 (Browser)"
WScript.Echo "Example: ChangeSQLServiceAccounts.vbs .
MSSQLServer 1 BuiltIn\System NULL"
WScript.Quit(1)
Else

' Load the inputs into variables.

strComputer = oArgs(0)
strInstanceName = oArgs(1)
strServiceType = oArgs(2)
strAccountName = oArgs(3)
strPassword = oArgs(4)
End If

' Get a WMI object for the SQL namespace.

Set objWMIService = GetObject("winmgmts:" &
"{impersonationLevel=impersonate}!\\" & strComputer &
"\ROOT\microsoft\sqlserver\ComputerManagement")

' Get an instance for this specific service.

Set objSQLService = objWMIService.Get("SqlService.ServiceName=""" &
strInstanceName & """,SQLServiceType=" & strServiceType)

' Obtain an InParameters object specific to the SQLService.SetServiceAccount
method.

Set objInParam =
objSQLService.Methods_("SetServiceAccount").inParameters.SpawnInstance_()

' Add the input parameters to the input object.

objInParam.Properties_.item("ServiceStartName") = strAccountName
objInParam.Properties_.item("ServiceStartPassword") = strPassword

' Call the SetServiceAccount method, and pass in the input object.

Set objOutParams = objSQLService.ExecMethod_("SetServiceAccount", objInParam)

'Check the return to see whether there were any errors.

If objOutParams.ReturnValue = 0 Then
Wscript.Echo "The service account was changed to " & strAccountName
Else
Wscript.Echo "Could not change the service account to " & strAccountName
& " due to error " & objOutParams.ReturnValue
End If

Whithin this class:
$class=[WMICLASS]'\\.\root\Microsoft\SqlServer\ComputerManagement:SqlService'

There's a method named setserviceaccount().

I've not used WMI enough, especially with methods, to figure out how to
invoke the method in this case.

Doing $class.psbase gives me a invokemethod() method, but I've not been
able to figure out the syntax or whether I'm on the right track.

Answered my own question, thought I'd share the script:

# Copyright Buck Woody, 2007
# All scripts provided AS-IS. No functionality is guaranteed in any way.
# Change Service Account name and password using PowerShell and WMI
$class = Get-WmiObject -computername "SQLVM03-QF59YPW" -namespace
root\Microsoft\SqlServer\ComputerManagement -class SqlService
#This remmed out part shows the services - I'll just go after number 6 (SQL
Server Agent in my case):
# foreach ($classname in $class) {write-host $classname.DisplayName}
# $class[6].DisplayName
stop-service -displayName $class[6].DisplayName
# Note: I recommend you make these parameters, so that you don't store
passwords. At your own risk here!
$class[6].SetServiceAccount("account", "password")
start-service -displayName $class[6].DisplayName
