The latest and greatest PowerShell v2 CTP2 requires a new WinRM 2.0 CTP so that remoting will work on Vista SP1 and Windows Server 2008. As Aleksandar Nikolic pointed out to me last week, it appears the WinRM CTP won't install on Server Core.
All I see is a message stating "The update does not apply to your system".
I've just fired off an email to the WinRM PM at Microsoft to get her feedback on this issue.
