the post specifically states R2 and 2012. It does not list WS2008.

I am assuming that is a typo.

You can use the CmdLets on R2 to access a standard 2008 IIS.

Yes but we both shouldn't assume anything, and since we haven't heard back from the OP, that is all we can do.

Yes you are correct, Win 2008 R2 and greater, you just need to enable the feature and then either Import-Module WebAdministration for Powershell 2.0 or just use the cmdlets with Powershell 3.0 or above and it will automatically import the module.

If it is also required to be on Win 2008 Standard, then the OP must install the add on, and then do a Add-PSSnapin WebAdministration in order to access the cmdlets.
