Thanks to Creamhackered over at Neowin.net for the Info:
We've received some information and screenshots on Yukon Beta 2. It seems Microsoft has been working steadily on Yukon since it's release to testers in July 2003. That was Beta 1 and this is Beta 2. We're not sure if this build (2000.090.0757.00) was the first build to be tagged Beta 2 but according to documentation and the installer screenshots we've received it's definitely Beta 2. Included in this build is the .NET Framework 2.0 which has previously only been available for Longhorn.
