How to update existing IIS 6 Web Site using PowerShell

First of all, big thanks to jrista for pointing me in the right direction.

I also found this article very useful.

What follows here is a powershell script to create Application pool, Website and a SelfSsl certificate:

function CreateAppPool ([string]$name, [string]$user, [string]$password){    # check if pool exists and delete it - for testing purposes    $tempPool  = gwmi -namespace "root\MicrosoftIISv2" -class "IISApplicationPoolSetting" -filter "Name like '%$name%'"    if (!($tempPool -eq $NULL)) {$tempPool.delete()}    # create Application Pool    $appPoolSettings = [wmiclass] "root\MicrosoftIISv2:IISApplicationPoolSetting"    $newPool = $appPoolSettings.CreateInstance()    $newPool.Name = "W3SVC/AppPools/" + $name    $newPool.WAMUsername = $user    $newPool.WAMUserPass = $password    $newPool.PeriodicRestartTime = 1740    $newPool.IdleTimeout = 20    $newPool.MaxProcesses = 1    $newPool.AppPoolIdentityType = 3    $newPool.Put()}function CreateWebSite ([string]$name, [string]$ipAddress, [string]$localPath, [string] $appPoolName, [string] $applicationName){    # check if web site exists and delete it - for testing purposes    $tempWebsite  = gwmi -namespace "root\MicrosoftIISv2" -class "IISWebServerSetting" -filter "ServerComment like '%$name%'"    if (!($tempWebsite -eq $NULL)) {$tempWebsite.delete()}    # Switch the Website to .NET 2.0    C:\windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -sn W3SVC/    $iisWebService  = gwmi -namespace "root\MicrosoftIISv2" -class "IIsWebService"    $bindingClass = [wmiclass]'root\MicrosoftIISv2:ServerBinding'    $bindings = $bindingClass.CreateInstance()    $bindings.IP = $ipAddress    $bindings.Port = "80"    $bindings.Hostname = ""    $iisWebService.CreateNewSite($name, $bindings, $localPath)    # Assign App Pool    $webServerSettings  = gwmi -namespace "root\MicrosoftIISv2" -class "IISWebServerSetting" -filter "ServerComment like '%$name%'"    $webServerSettings.AppPoolId = $appPoolName    $webServerSettings.put()    # Add wildcard map    $wildcardMap = "*, c:\somewildcardfile.dll, 0, All"    $iis = [ADSI]"IIS://localhost/W3SVC"    $webServer = $iis.psbase.children | where { $_.keyType -eq "IIsWebServer" -AND $_.ServerComment -eq $name }    $webVirtualDir = $webServer.children | where { $_.keyType -eq "IIsWebVirtualDir" }    $webVirtualDir.ScriptMaps.Add($wildcardMap)    # Set Application name    $webVirtualDir.AppFriendlyName = $applicationName    # Save changes    $webVirtualDir.CommitChanges()    # Start the newly create web site    if (!($webServer -eq $NULL)) {$webServer.start()}}function AddSslCertificate ([string] $websiteName, [string] $certificateCommonName){    # This method requires for you to have selfssl on your machine    $selfSslPath = "\program files\iis resources\selfssl"    $certificateCommonName = "/N:cn=" + $certificateCommonName    $certificateValidityDays = "/V:3650"    $websitePort = "/P:443"    $addToTrusted = "/T"    $quietMode = "/Q"    $webServerSetting = gwmi -namespace "root\MicrosoftIISv2" -class "IISWebServerSetting" -filter "ServerComment like '$websiteName'"    $websiteId ="/S:" + $webServerSetting.name.substring($webServerSetting.name.lastindexof('/')+1)    cd -path $selfSslPath    .\selfssl.exe $addToTrusted $certificateCommonName $certificateValidityDays $websitePort $websiteId $quietMode}$myNewWebsiteName = "TestWebsite"$myNewWebsiteIp = "192.168.0.1"$myNewWebsiteLocalPath = "c:\inetpub\wwwroot\"+$myNewWebsiteName$appPoolName = $myNewWebsiteName + "AppPool"$myNewWebsiteApplicationName = "/"$myNewWebsiteCertificateCommonName = "mynewwebsite.dev"CreateAppPool $appPoolName "Administrator" "password"CreateWebSite $myNewWebsiteName $myNewWebsiteIp $myNewWebsiteLocalPath $appPoolName $myNewWebsiteApplicationNameAddSslCertificate $myNewWebsiteName $myNewWebsiteCertificateCommonName

The $result object contains the path to the newly created IIsWebServer object. You can get access to the virtual directory, where you can configure more properties, by doing the following:

$w3svcID = $result.ReturnValue -replace "IIsWebServer=", ""$w3svcID = $w3svcID -replace "'", ""$vdirName = $w3svcID + "/ROOT";$vdir = gwmi -namespace "root\MicrosoftIISv2"              -class "IISWebVirtualDir"              -filter "Name = '$vdirName'";# do stuff with $vdir$vdir.Put();

This is a useful PowerShell snippet.

I tried running this and I get problems with the delete tests. Delete does not work against the app pool when the site still exists. Surely you should run website delete test first.

# check if web site exists and delete it - for testing purposes$tempWebsite  = gwmi -namespace "root\MicrosoftIISv2"                      -class "IISWebServerSetting"                      -filter "ServerComment like '%$name%'"if (!($tempWebsite -eq $NULL)) {$tempWebsite.delete()}

Run this first, then run the app pool deletion test.
I realise you have marked these as tests but surely it is useful to exit or delete if webs site exists.
