Ok i'll see what they say. A TS CAL and a server access CAL I can deal with it's the OS CAL bit that I can't (staring thoughtfully accross the room at the Ubuntu play box)
I think the confusion is that you are thinking of the desktop license being just for the Windows upgrade license. Under Schools Agreement, you purchase a desktop pack with core CALs (or Enterprise CALs) and this gives you the following:
* Windows OS upgrade license
* Your selected CAL pack - see http://www.microsoft.com/calsuites/e...s/default.aspx for details of what that includes
If you run 'Remote Desktop Services' you will also need to license for that.
So if you have a mix of thin and fat clients you simply add them all up and purchase that many desktop licenses and that many RDS CALs.
We're going to be looking at the SESP licensing this year, which seems to be what Microsoft are trying to combat the issues people had with thin clients. http://www.microsoft.com/uk/educatio...t/default.aspx. From what I understand, you can license bits of the school for bits of licensing (so only as many RDS CALs as needed for devices accessing TS, only as many Desktop licenses as required for fat clients).
However, there doesn't seem to be mention of licensing Office separately (which you'd probably need for machines accessing the TS). May be another option to ask your licensing supplier about.
@Willott: I looked into SESP when I got my Schools Agreement and prices weren't really any different for what I needed... plus only a couple of resellers could offer it, reducing competition!
Speaking to Microsoft direct, I also discovered that they would prefer you to use a Schools Agreement over SESP (at least at the moment) so that you are entitled to other benefits.
I also believe that there's a push at the moment to get people away from SELECT onto Schools Agreement... your reseller can probably tell you more (Faith Warburton at Insight just happened to mention it to me during a conversation the other day).
