My take: Per user would be your best bet unless in a situation where you've got maybe a couple terminals which are accessed by a large number of users...then device licensing is the way to go. Other than that, per user would be the right direction to take. -----Original Message----- From: Schneider, Chad M [mailto:CMSchneider@xxxxxxxxx] Sent: Tuesday, May 17, 2005 3:54 PM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] WIN2K3 TS CALS As I move to WIN2K3 for my farm, I have a 2003 AD DC with TS Licensing running on it. It is currently dispensing WIN2K TS Cals. I want to be able to use the WIN2K3 server, so I gather I need 2K3 TS Cals, to connect to 2K3 TS/Citrix servers. Should I choose per client or per user licensing? Why? What is more efficient/robust? I am thinking per user is the better bet. Chad M. Schneider Technology Analyst Bemis Corporate IT 920-303-7609
