What is the cheapest edition of Windows that can act as a Domain Controller?

Solution
Depends on how many users you need - if 25 is enough, Server 2012 R2 Essentials (i.e. the new "small business edition") should be OK. Otherwise 2012 R2 standard, or get a 2008 R2 if you still can. Anything server 2003 and older is out of the question (support ending soon / already ended).
If you do not care about hotfixes, technically any old Windows server 2000 would be able to act as a DC, though of course not with the latest version of the active directory.

Thanks. 2003 would actually be OK for me, I'm setting this up as a testing lab in my home just so I can play around with things before I do them for real at work :D. My "users" are basically going to be one desktop, one laptop, and a couple of mobile devices.
