Be aware that you may need to consider the licensing implications of providing external access e.g. a website, extranet etc
Things can get troublesome with terminal server, especially if what you really want is something along the lines of "I want up to X people to be able to connect, but I don't care who they are or where they are connecting from".
This is quite a pertinent topic for us as we have just rolled out our first MS server in the school to host the office network. But over the summer, we have a new ICT suite coming online and upgrading to a school reporting system that will be rolled out to the teachers as well as the current office staff.
Presently we decided on device CALs for the office suite, but the technicalities of licensing, a change in license supplier by Surrey County Council and, the direction of the school reports system shifting to the teachers working from home has recently led me to reassess our licensing options. Infact, it it one of my jobs today.
We have available to us, two licensing models.
1. Perpetual licenses - Select Agreement
2. A subscription based license - Schools ProDesktop
The perpetual licenses are available as Device CAL, User CAL or, something that I had not realised, a mix of both.
We have approx 30 staff and 120 students, all of whom need to be licensed even though the younger pupils do nothing more than doodle on a group PC.
So one of our options is to license all the student accessible PC's as device CAL's ie the ICT suite and some classroom PC's, then license all the staff with User CALs. This will bring our licensing requirements down to approx 60 units and allow staff to access the reporting system from home as they are user based CALs.
The subscription based license is device based and one subscription is needed per desktop in the school. Servers are licensed separately either as a subscription based model, or a perpetual model. As it is a whole school agreement, its an all or nothing agreement so we cannot mix and match to different PC's - many of our PC's are legacy and will not run Office etc or benefit from software assurance which allows us to upgrade versions of the OS or applications. Even though this is device based, staff get work at home rights, which solves the problem of not being able to license a home PC with a school device CAL - putting it simply, you cannot license a device that you do not own, ie a home PC.
Something I had not realised until reading this thread was that printers counted as device CALs. We have a networked photocopier with the server acting as print server. Thankfully we ordered a few spare CALs for the office so are covered until we need to make the decision about rolling out the rest of school.
But does anyone know if a printer needs a device CAL if it is local to a PC but shared and deployed via group policy?
My best advice though (as a few people have already said) is to give your reseller a call and see what they say about it. :)
