Howto créer un Répertoire Virtuel IIS à l'aide d'un réseau de partager avec WMI

## Settings
$siteName = 'Default Web Site'
$virtualDirectoryName = 'Test'
$physicalPath = '\\UNC-path'

## Init
$virtualDirectoryPath = "IIS:\Sites$siteName$virtualDirectoryName"

## Create Virtual Directory where physicalpath is an UNC-path (New-WebVirtualDirectory wont do)
New-Item $virtualDirectoryPath -type VirtualDirectory -physicalPath $physicalPath

## Change 'Connect As' settings (New-WebVirtualDirectory don't include Username and Password)
##userName must have the N capitalized
Set-ItemProperty $virtualDirectoryPath -Name userName -Value 'UserName'
Set-ItemProperty $virtualDirectoryPath -Name password -Value 'Password'

## Status
Get-Item -Path $virtualDirectoryPath | fl *

Voici deux alternatives powershell fonctions, je suis venu avec. Je préfère la deuxième fonction qui n'utilise WMI mais le Powershell et WMI défaut d'erreur m'a ennuyé assez que j'ai eu recours à l'aide de l'interface ADSI. Les deux sont inclus à titre de référence.

function CreateUNCVirtualDirectory(
[string]$siteName = $(throw "Must provide a Site Name"),
[string]$vDirName = $(throw "Must provide a Virtual Directory Name"),
[string]$uncPath = $(throw "Must provide a UNC path"),
[string]$uncUserName = $(throw "Must provide a UserName"),
[string]$uncPassword = $(throw "Must provide a password")
) {
$iisWebSite = Get-WmiObject -Namespace 'root\MicrosoftIISv2' -Class IISWebServerSetting -Filter "ServerComment = '$siteName'"
$objIIS = new-object System.DirectoryServices.DirectoryEntry("IIS://localhost/" + $iisWebSite.Name + "/Root")
$children = $objIIS.psbase.children
$vDir = $children.add($vDirName,$objIIS.psbase.SchemaClassName)
$vDir.psbase.CommitChanges()
$vDir.Path = $uncPath
$vDir.UNCUserName = $uncUserName
$vDir.UNCPassword = $uncPassword
$vDir.psbase.CommitChanges()
}
