At this week's WinHEC 2007 conference in Los Angeles, Microsoft gave the final name of what was previously known only as Windows Server codename "Longhorn." Windows Server 2008, which recently reached the Beta 3 milestone, is expected to be available in four different editions: web, standard, enterprise, and datacenter. Windows Server 2008 builds on the improved reliability, security and manageability of Windows Server 2003 R2 to help alleviate pressures on IT professionals today by adding enhancements to further automate daily management tasks, tighten security, provide a more extensible platform for hosting and Web applications, improve efficiency, and increase network availability. The final version of the operating system will be released later this year.
