Earlier today I posted that R2 is now available but I inadvertently left out one minor detail - The posted download is the eval version only. It clearly states this on the site but I probably should have made that more clear in my post. Sorry to get your hopes up. Also, the R2 Eval requires the Site to be at the SP1 eval version. This will not install on a full SP1 site and you may receive this error:
“You can only install on an SCCM SP1 eval installation"
This is all because R2 is not a free add-on for Configuration Manager and the bits that are available are simply there so the product can be evaluated for a limited time. The error above can actually be viewed as a good thing because it prevents you from installing evaluation bits in a production environment - not a good thing when the expiration date comes around.
Anyway, for the specifics, when you click through to the download page (http://www.microsoft.com/downloads/details.aspx?FamilyId=7376214F-CBA3-4E0D-81FE-AD52488BE3A3&displaylang=en) please pay close attention to the System Requirements where this is noted:
- Supported Operating Systems: Windows 2000 Service Pack 4; Windows Server 2003 R2 Enterprise Edition (32-Bit x86); Windows Server 2003 R2 Standard Edition (32-bit x86); Windows Server 2003 Service Pack 1; Windows Server 2008 Enterprise; Windows Server 2008 Standard; Windows Vista Business; Windows Vista Enterprise; Windows Vista Ultimate; Windows XP Embedded; Windows XP Service Pack 2
-------> System Center Configuration Manager 2007 SP1 Evaluation <-------
I added the arrows for emphasis. And if you're looking for more detailed requirements see Supported Configurations.
Thanks to Clifton Hughes for bringing this to my attention, and if you're looking to purchase the full retail version of ConfigMgr 2007 R2 then you can pursue that through your regular sales channel.
