Michael Otley wrote a post entitled "Top 15 Windows Server Innovations In the Past 15 years"; "Since Microsoft released Windows NT, MS has made huge improvements and added hundreds of new features to OS. Back in 1993, Windows NT initially competed with OS/2 as a native 32-bit desktop OS. Since that time, Windows Server has evolved into 64-bit server standard that's used by almost all businesses."
Here's a quick list: Active Directory (AD), Group Policy, Resultant Set of Policy (RSOP), Volume Shadow Copy Services (VSS), Windows SharePoint Services—Windows 2003 R2, Server Manager—Windows Server 2008, Server roles and features, Server Core, Hyper-V, Windows BitLocker Drive Encryption, Support for 256 cores—Server 2008 R2, Hyper-V Live Migration, Core Parking, RemoteFX, and Dynamic Memory Allocation.
….TCP/IP – Microsoft first released their version of TCP/IP for Windows 3.5 in September of 1994 which's technically 16 years ago, not within 15 year Window, (pun intended) however this's the single most important innovation in the history of Windows Server. Had Microsoft chosen to stay with NetBEUI we would have never made the leap into the mainstream server marketplace….Chris Henley.
