Hi,

I'm trying to stop an applicaion pool in IIS 7 remotely using PS v2.

I've installed the webadministration cmdlets, and can easily maintain IIS locally.  But, when I attempt to run anything remotely I recieve errors stating that the cmdlet I am running is not recognised - I have enabled PS Remoting, and can run other cmds on the machine using New-PSSession.

Can anyone point me in the right direction as to what I am doing wrong please?  Here is the part of the script I am working on at the moment.

[System.Reflection.Assembly]::LoadFrom( "C:\windows\system32\inetsrv\Microsoft.Web.Administration.dll" )
$Session = New-PSSession -ComputerName 'QPROVA02'
Invoke-Command -Session $Session -ScriptBlock { import-module 'webAdministration'; Stop-WebAppPool 'manageUsers' }


thanks in advance.

Robbie.

You're loading the dll locally, but expecting to call it remotely. You'll need to load the dll in the remote session.

$Session = New-PSSession -ComputerName 'QPROVA02'

$block = {
[System.Reflection.Assembly]::LoadFrom( "C:\windows\system32\inetsrv\Microsoft.Web.Administration.dll" )
import-module 'webAdministration'
Stop-WebAppPool 'manageUsers'
}

Invoke-Command -Session $Session -ScriptBlock $block

You can remove the LoadFrom() call. The WebAdministration module loads all the necessary DLL's for you.

I tried both ideas, and got the same error.

Basically saying the start-webapppool is not a valid cmdlet.

Try interactively:

Enter-PSSession QPROVA02
import-module webAdministration
Stop-WebApp[ PRESS TAB]

The command is tab completed?

ok tried that...  Getting the same error.

Import-Module : The specified module 'webAdministration' was not loaded because
 no valid module file was found in any module directory.
    + CategoryInfo          : ResourceUnavailable: (webAdministration:String)
   [Import-Module], FileNotFoundException
    + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Comm
   ands.ImportModuleCommand

Then (obviously)

The term 'stop-webapppool' is not recognized as the name of a cmdlet, function,
 script file, or operable program. Check the spelling of the name, or if a path
 was included, verify that the path is correct and try again.
    + CategoryInfo          :
    + FullyQualifiedErrorId : CommandNotFoundException

What I have also tried is running the same cmds from the box itself, which has produced the same result.  Would that make any difference?  I didn't think it would as PS would just open another session over the network??

Perhaps re-installing the web admin cmdlets again??  I've ran out of knowledge / options now.

But to answer your question...  No - Tabbing the cmd doesn't initialize the cmdlet.

Do you get a result when you run the following inside the session:

Get-Module WebAdministration -ListAvailable

No

PS C:\> get-module webadministration -listavailable
PS C:\>

Then the webadministration module doesn't exist on the target.

I can use the cmdlets locally on it no problem... Is there a posibility they are named something else?

I am a little confused here as I can use the cmdlets - for example start / stop-webAppPool when I am on the server itself. It works perfectly.

Do you think removing them, and re-installing might offer some relief?

How do you load the module when you're working locally on the server? 'gmo web* -list' returns the module?

It's quite odd...

ModuleType Name ExportedCommands
---------- ---- ----------------
Manifest BitsTransfer {}
Manifest PSDiagnostics {Enable-PSTrace, Enable-WSManTrace, Start-Trace, Disable-PSWSManCombined...


PS C:\Users\da-rdixon> start-webapppool manageusers
PS C:\Users\da-rdixon>

does this mean that the module is not loading? If so how can I run the cmd - i checked it in IIS GUI, and the app pool was definately started when it was stopped.

I don't actually manually load the module, I open the powershell modules interface and that loads them for me.

I also tried the power gui from quest software to see if I could load the libraries through it, and it works fine too. Unless I try remote connection, which is my objective.

What's the OS type on the remote server?

2008 64x...

You need to install the IIS powershell provider:

http://www.iis.net/download/PowerShell

I have this installed. I can run the cmdlets when I am on the server itself no problems at all.

I guess trying a re-install might work.

I didn't work.

Does the webadministration module need to be installed on the local server?

I mean, I only have it installed on the server I am connecting to then running the script against.

FINALLY!!!
$Session = New-PSSession -ComputerName QPROVA02
Invoke-Command -Session $Session -ScriptBlock { Add-PSSnapin webadministration ; start-webapppool manageusers }

Life is good!

Thanks for the aid Shay - I honestly didn't have a clue how to do it, but you pointed me in the right direction!

Rob :-)

Awesome :)

This error should have told you that the WebAdministration module is not installed on the remote server. I assume you eventually came to this conclusion but I wanted to point this out explicitly here in case somebody else runs into this issue.

EDIT: This should teach me to read all pages on a topic... The other posts already covered this...
