The next version, Windows NT Server 3. This version enhanced the server functionality to support interconnectivity with both Unix systems and Novell NetWare. Because Unix and Novell servers were the standards at the time, this approach was essential for Windows NT Server to be competitive in the market.

The interconnectivity meant servers with the Windows operating system could be incorporated in an existing network running on Unix or Novell. Windows NT Server 3. The server version supported computers running Windows 95 and provided some improvements to make the system more stable.
