MIcrosoft Licensing Requirements

I have a question about licensing Microsoft software.

In my company I have 3 servers running Windows 2003

- Exchange Server
- Terminal Services Server
- Domain Controller

I also have about 30 workstations running Windows XP.

Now if I understand MS licensing correctly I need to have 3 Windows 2003 Server Standard licenses for these. On top of that I need my server license for exchange as well as my 30 CALs for Exchange. I also need 30 Terminal Server CALs. Do I need anything else? Do I need Windows 2003 Server CALs? If so which option is better for my environment: Per Sear or Per Server.

Someone told me if I chose per seat and purchased the appropriate CALs then I wouldn't need 3 Windows 2003 Server Standard licenses but I don't think that is accurate. This whole thing has my head spinning.

Once you get above one server - per seat is always the best because it is is cheapest.

For Windows you always need BOTH OS and CALs.
In most cases, number of workstations = number of CALs required.
That applies to both Windows Server CALs and Exchange CALs.

Where the confusion may have come from is that Windows OEM server licenses come with 5 Windows Server CALs. However if you buy Windows Server OS licenses on volume then they do not come with CALs.

Windows and Exchange CALs are on the honour system - there is no count.
Terminal Services CALs are hard enforced by the TS licensing service.

Obviously everything I have said above is not legal advice - the only people who can answer your question accurately are Microsoft. When they do, ask them to confirm it in writing.

OK so if I understand this correctly I would need the following:

3 Windows 2003 Server OS licenses
1 Exchanges Server license

30 Exchange CALs
30 Terminal Server CALs (per device model)
30 Windows CALs (per seat model)

Does that sound correct?

That is what I would purchase.
The terminal services licensing server would go on to a domain controller.

Aside from licensing, I would actually suggest a second domain controller. Not the Exchange server or the terminal services server, but a separate machine. One DC is putting a lot at risk if it fails.
