Vista - WMI in IIS 6.0

Hello,

I am trying to create a new website on IIS 6.0. I have successfully
completed this task using VBScript, but I’m struggling converting the code
into Powershell, because I am newbie to WMI and fairly new to Powershell. My
VBScript code is as follows:

set locatorObj = CreateObject("Wbemscripting.SWbemLocator")
set providerObj = locatorObj.ConnectServer("localhost",
"root/MicrosoftIISv2")
set serviceObj = providerObj.Get("IIsWebService='W3SVC'")

Bindings = Array(0)
Set Bindings(0) = providerObj.get("ServerBinding").SpawnInstance_()
Bindings(0).IP = ""
Bindings(0).Port = "8383"
Bindings(0).Hostname = ""

Dim strSiteObjPath
strSiteObjPath = serviceObj.CreateNewSite("MyNewSite", Bindings,
"C:\Inetpub\Wwwroot")


I have tried to convert the variable declaration and object instantiation to
the following:
$locatorObj = new-object -com WbemScripting.SWbemLocator
$providerObj = $locatorObj.ConnectServer("localhost","root/MicrosoftIISv2")
$serviceObj = $providerObj.Get("IIsWebService='W3SVC'")

This conversion does not provide a build error but when I try to invoke the
CreateNewSite() on the $serviceObj variable I get an error explaining that
$serviceObj does not contain a function or method CreateNewSite(). This is
strange because I reckon it should, considering WMI is supported by
Powershell.

So I’m guessing there is a problem passing “root/MicrosoftIIsv2� to
$locatorObj.ConnectServer but I’m not entirely sure what to pass as an
alternative.

If anyone can explain where I’m going wrong, or provide some direction or
even convert the VBScript code snippet for me I’d be very much
appreciative.

Thanks in advance,

While I don't profess to be a wbem/wmi ninja, I can help you here - an
explanation of the techniques is worth a blog entry in itself (I've
started writing it now, so I'll post back to this thread when it's
done) so for the moment, I've written how this is performed using what
MS refer to as "indirect method calls." Some languages, like vbscript
allow "direct" calls like your example above. It doesn't appear [to
me] that powershell has a fully featured adapter for this kind of
stuff yet, but the powershell team has done an otherwise excellent job
in enabling COM interop as it is - anyway, try this out:
# get reference to method# define "in" parameters# execute method# display resultQualifiers_ : {}
Properties_ : {ReturnValue}
Methods_ : {}
Derivation_ : {}
Path_ : System.__ComObject
Security_ : System.__ComObject
SystemProperties_ : {__PATH, __NAMESPACE, __SERVER, __DERIVATION...}

This was tested on Windows 2003 SP1. This will NOT work on Windows XP.

For more information on indirect method usage, see:

Hope this helps,

Marco's link (posted while I was preparing the last post) and I see
that you _can_ call the methods directly via PSBase. LOL - like I
said, I ain't no WMI ninja anyway...

Anyway, hopefully it demonstrates something useful!

already and don't feel like changing the whole thing, you can quickly
get a powershell "adapted" version using the [wmi] accelerator against
the path, e.g.
# get adaptedr versionTypeName: System.Management.ManagementObj...

Name MemberType Definiti
---- ---------- --------
AddDependency Method System.M...
AddExtensionFile Method System.M...
Change Method System.M...
ChangeStartMode Method System.M...
Create Method System.M...
CreateNewSite Method System.M...
DeleteExtensionFileRecord Method System.M...

As you can see, the methods are now available in "direct" style
(without needing psbase it appears)?

Hey Oisin,

Yeah Marco's link was pretty useful and helped solve my problem. Thanks for
your input though, never have too much info especially when i'm new to WMI
and trying to fudge my way through it

Cheers,
