Do you need to purchase Microsoft CALS for a 3rd party application being hosted?
I have a new Windows 2003 Server that is a member of an AD domain. I have per user licensing setup for my 200 users. I want to run Groupwise for e-mail on the new server. Do I need to purchase new CALS for this? If I was per seat instead of per-user - would I still need to purchase more CALS?
