Thanks to Creamhackered for letting me know of this. Apparently, build 3716 of Microsoft's .Net Server 2003, which was available to testers a few days ago has been leaked and running around wildly on the internet.
Here's a snippet from WinBeta.org:
With RC2 on the horizon for next week, this latest build currently available to beta testers seems to be a nice stepping stone up the ladder to the next release candidate.
Windows .NET Server 2003 includes all the functionality customers expect from a mission-critical Windows server operating system, such as security, reliability, availability, and scalability. In addition, Microsoft has improved and extended the Windows server operating systems to enable your organization to experience the benefits of Microsoft .NET—software for connecting information, people, systems, and devices.
