I am upgrading a terminal server in a real estate agency. There are 70+ users but only around 30 workstations. Most of the office is shared where agents just come in and sit down at an empty desk where there are thin clients for logging into the server.
Have 35 CALs but on average there are about 10 active sessions.
The new server will be running RDS on 2008 R2 and I have found that i need to use a volume license for Office 2010.
My question is: what do i base the amount of licenses on?
The total amount of users, client machines or max concurrent sessions?
