Windows Longhorn build 4093 (Lab02 N)

Windows Longhorn build 4093 (Lab02_N) is an unleaked build of Windows Longhorn. It was referenced in the file  in the Driver Development Kit for Windows Server 2003 Service Pack 1 and onwards. It is the latest confirmed build of pre-reset Longhorn. Notably, it has a compile date of October 2004, later than the builds of the post-reset Omega-13 branch. Thus, it is possible that pre-reset Longhorn was kept around as a fallback had the post-reset codebase proved unsuitable.
