Windows NT 3.5

[7] (Its predecessor, Windows NT 3.1, only includes an incomplete implementation of TCP/IP based on the AT&T UNIX System V "STREAMS" API.)

It can act as a Gopher, HTTP, or WAIS server,[11] and includes Remote Access Service for remote dial-up modem access to LAN services using either SLIP or PPP protocols.

[12] Windows NT 3.5 Resource Kit includes the first implementation of Microsoft DNS.

[14] Microsoft updated the graphical user interface to be consistent with that of Windows for Workgroups 3.11.

[4] A lack of drivers for PCMCIA cards limited NT 3.5's suitability for notebook computers.
