I have a single SBS 2011 that I need multiple users to be able to log into via Terminal Services. Apparently, this is not possible in the Standard Edition. It seems as though I can enable this feature with the Premium Addon (see http://social.technet.microsoft.com/wiki/contents/articles/8592.sbs-2011-premium-add-on-faq.aspx
Q "Can I install and use Windows Server Remote Desktop Server (RDS) Session Host on my Premium Add-on server?"). I can't seem to find out how I can add this to my existing installation. Is it simply a serial number that needs to be inputted in order to activate the additional features? Sorry if this is a silly question.
