Powershell: Setting anonymous user in IIS6

Question

I'm using the PowerShell script below to set anonymous user identity and authentication methods on an IIS6 server. The script seems to work at first, but if I issue an iisreset after running it the values revert to the old ones! How do I persist them?

 $server = "localhost"
 $siteName = "www.mysite.com"
 $iis = [ADSI]"IIS://$server/W3SVC"
 $site = $iis.children | where { $_.keyType -eq "IIsWebServer" -and $_.ServerComment -eq $siteName }
 $path = [ADSI]($site.path+"/ROOT")
 $path.AnonymousUserName = "user"
 $path.AnonymousUserPass = "pass"
 $path.AuthFlags = 3
 $path.CommitChanges()

Answer 1

Turns out the metabase is not persisted at once. iisreset forces shutdown of the IIS services and the information is lost.

There are two ways of fixing this:

1. Run C:\WINDOWS\system32\IIsCnfg.vbs /save
2. net stop and then net start
