Windows NT 5
(Win2k, W2k, NT5, Windows NT 5.0) An
operating system developed by Microsoft Corporation for
PCs and servers, as the successor to Windows NT 4.0.
Early beta versions were referred to as "Windows NT 5.0".
Windows 2000 was officially released on 2000-02-17.
Windows 2000 is most commonly used on Intel x86 and
Pentium processors, with a DEC Alpha version rumoured.
Unlike Windows NT 4.0, Windows 2000 is not available for
PowerPC or MIPS.
Windows 2000's user interface is very similar to Windows
95 or Windows NT 4.0 with integrated Internet Explorer, or
to Windows 98.
It is available in four flavours:
- Professional: the client version, meant for desktop
workstations, successor to Windows NT Workstation.
- Server: "entry-level" server, designed for small
deployments, and departmental file, print, or intranet
- Advanced Server: high throughput, larger scale servers
and applications, and small to medium scale websites.
- Data Center Server: software for large-scale server
clusters (in development as of 2000-03-14).
New features in Windows 2000 include:
- Active Directory.
- Greatly improved built-in security mechanisms, including
Kerberos-based authentication, public key support, an
encrypting file system, and IPsec support.
- Integrated web browser - Internet Explorer 5.0.
- Integrated web server - IIS 5.0
- Terminal services for displaying application interfaces on
remote computers (similar to X-Windows).
