Windows NT 3.5 is the second major release of the Windows NT operating system developed by Microsoft, targeting the data server and personal workstation markets.{{cite thesis |url=http://dspace.qau.edu.pk:8080/jspui/bitstream/123456789/29833/1/COM%201354.pdf |title=Geographic Information System for Capital Development Authority |author=Aftab Nazir Ahmed |publisher=Quaid-I-Azam University |page=46}} It was released on September 21, 1994, as the successor to Windows NT 3.1. One of the primary goals during its development was to improve the operating system's performance. As a result, the project was codenamed "Daytona", after the Daytona International Speedway in Daytona Beach, Florida.{{Cite book |title=Microsoft Windows Internals |last1=Russinovich |first1=Mark |last2=Solomon |first2=David A. |date=8 December 2004 |publisher=Microsoft |isbn=978-0-7356-1917-3 |edition=4 |quote=The first release of Windows NT was larger and slower than expected, so the next major push was a project called "Daytona", named after the speedway in Florida.

Features
Windows NT 3.5 comes in two editions: NT Workstation and NT Server.

Windows NT 3.5 can share files via the File Transfer Protocol, and printers through the Line Printer Daemon protocol. It can act as a Gopher, HTTP, or WAIS server,{{cite web |url=http://www.yale.edu/pclt/WINWORLD/NT.HTM |title=TCP/IP in Windows NT 3.5 |date=9 April 1995 |website=Yale.edu |publisher=Yale University |access-date=22 September 2013 |archive-date=29 February 2000 |archive-url=https://web.archive.org/web/20000229122839/http://www.yale.edu/pclt/WINWORLD/NT.HTM |url-status=live }} and includes Remote Access Service for remote dial-up modem access to LAN services using either SLIP or PPP protocols.{{cite web |url=http://support.microsoft.com/kb/142909 |title=Files Needed to Set Up Windows NT 3.5 and 3.51 RAS |date=1 November 2006 |website=Microsoft |access-date=22 September 2013 |archive-date=25 December 2013 |archive-url=https://web.archive.org/web/20131225113444/http://support.microsoft.com/kb/142909 |url-status=live }} Windows NT 3.5 Resource Kit includes the first implementation of Microsoft DNS.DNSSETUP.EXE for Beta DNS Service included in ftp://ftp.microsoft.com/bussys/winnt/winnt-public/reskit/nt35/i386/i386.exe{{Dead link|date=February 2022 |bot=InternetArchiveBot |fix-attempted=yes }}
Other new features in Windows NT 3.5 include support for the VFAT file system, Object Linking and Embedding (OLE) version 2.0 and support for input/output completion ports.{{Cite web |url=http://www.microsoft.com/technet/sysinternals/information/IoCompletionPorts.mspx |title=Inside I/O Completion Ports |last=Russinovich |first=Mark |author-link=Mark Russinovich |date=1 November 2006 |website=Sysinternals |publisher=Microsoft |archive-url=https://web.archive.org/web/20070220042334/http://www.microsoft.com/technet/sysinternals/information/IoCompletionPorts.mspx |archive-date=20 February 2007}} Microsoft updated the graphical user interface to be consistent with that of Windows for Workgroups 3.11. NT 3.5 shows performance improvements over NT 3.1, and requires less memory.
Windows NT 3.5 added support for ATAPI CD-ROM. Windows NT 3.5 support for ISA PnP is not enabled by default.
Limitations
A lack of drivers for PCMCIA cards limited NT 3.5's suitability for notebook computers.
To install Windows NT 3.5 on a computer that has a sixth-generation or later x86 processor,{{cite web |title=Windows NT 3.5 Setup and the Pentium Pro Processor |url=http://support.microsoft.com/kb/151212/en-us |publisher=Microsoft |date=1 November 2006 |access-date=4 September 2009 |archive-date=25 February 2012 |archive-url=https://web.archive.org/web/20120225064332/http://support.microsoft.com/kb/151212/en-us |url-status=live }} one has to modify files on the installation CD-ROM.
Reception
In July 1995, Windows NT 3.5 with Service Pack 3 was rated by the National Security Agency as complying with Trusted Computer System Evaluation Criteria (TCSEC) C2 criteria.{{cite web |title=Windows NT Server 4.0 – Maintain – Revision 1.1 |url=https://technet.microsoft.com/en-us/library/cc767093.aspx |publisher=Microsoft |year=1998 |access-date=4 September 2009 |archive-date=28 February 2010 |archive-url=https://web.archive.org/web/20100228175254/http://technet.microsoft.com/en-us/library/cc767093.aspx |url-status=live }}
