Thanks to Bink for this one.
Build 3742 of Windows .Net Server 2003 has seaped through one of the many holes in microsofts bucket . The new build of Windows 2003 Server (Previous Windows .Net Server) is build 3742, and apparently runs alot smoother in terms of performance. This build is nearly 25 builds higher than the recently-released RC2. All 3 editions of the build have been leaked - i.e. Enterprise, Web Server, and Datacenter (why one would want this one does not know!). Although there are no new features, there are reportedly a few bug fixes.
