O.k. be warned, since following the Microsoft Windows Server division blog, was decided that by July 13 of 2010, Windows 2000 will no longer be publicly supported but will be able to continue using "Self-Help Online Support". And for Windows Server 2003 and Windows Server 2003 R2 (at a supported service pack level) will move from the Mainstream Support phase to the Extended Support phase, as well was confirmed that will be no Service Pack 3, so what you currently have is what you will have it going forward.
In any case to understand better those phases see the picture below to have a better idea of what those phases means and what kind of support you should expect:
So consider this for future testings, purchases and of course be sure what you will expect from support after July 2010
