That last is good for me ... we run a laptops for students scheme and purchase Office Pro for Student / Teacher. We are now starting to give access to the Terminal Server to students on these laptops. And staff access it via their laptops issued to them by school anyway. The only thing to be wary of is ensuring we have sufficient device licences to cover the thin clients.
External Connector Clarification
The current licensing definition refers to non-employees. We know this is not a simple definition to apply in an Education context, but for simplicity we take the following view here in the UK:
Teacher or Staff Member – CAL required
Student, Alumni, External User, Employer ....... – can all be licensed via an External Connector as an alternative to a CAL
We are hopeful that this will be further clarified and simplified in the coming months.
PC Operating System
Component changes such as memory, disk and graphics cards can all be upgraded without OS implications. The PC motherboard is the core component with which the OS is associated and so if this is upgraded/changed it is viewed as a different PC that either has an existing OS associated with it or requires one. If the Motherboard is being replaced under warranty, due to failure, then the OEM can legitimately re-install an OS and provide a Certificate of Authentication (COA). Check with your OEM or hardware provider if in doubt.
Terminal Server Licences
These cover access to the Windows Server. Office is licensed separately on either a user or device basis, whichever is more cost effective. If a user based at home has a locally licensed copy of Office then we will take a sensible view of this and not require an additional copy of Office to be purchased.
The other thing to look at are ‘Work at Home rights’ for teachers (no additional cost) and Student options. These can greatly reduce the licence burden for schools wishing to support remote access from home. Microsoft Education Resellers should be able to advise on the most cost effective options.
