Longhorn December 2006 CTP (Build 6001)
The Windows Server team released a new build of Windows Server Codename "Longhorn" to the Technical Beta participants a couple of days ago and named it the "December 2006 Community Technology Preview". According to Steven Bink the build number is 6001.
Technical Beta Participants
If you're a Technical Beta Participant you can download the x86 and x64 versions of the December 2006 CTP here.
Technet & MSDN subscribers
The December 2006 CTP will be made available to Technet and MSDN subscribers too when all systems are back online. (You may have read about the weather conditions in the Northwest Pacific region lately) This will probably be a week.
Before rushing into your test labs I'd like to point out this latest build of Windows Server Codename "Longhorn" isn't feature complete. For feature completeness you'd have to wait for the third beta, due H1 2007.
