![]() The kernel-mode driver links directly to one or more application pools. The HTTP.SYS service manages the client connections, bandwidth throttling, and Web server logging. You can configure HTTP.SYS to listen to specific TCP and UDP ports for inbound requests. HTTP.SYS sits directly on top of the TCP/IP protocol stack so that it can interact directly with the server’s TCP/IP connection. The IIS 6.0 kernel-mode driver (HTTP.SYS) is the point of contact for all inbound server requests. Now that you know about the three new components, I’ll discuss each in greater detail below. W3WP.EXE runs all Web application processes in an isolated worker process, in the name of system stability. The new components consist of a kernel-mode HTTP listener program called HTTP.SYS, a user-mode process and configuration manager called the Web Administration Service, and an application handler called W3WP.EXE. Rather than relying so heavily on INETINFO.EXE, IIS 6.0 is divided into three main components, each of which uses a new kernel-mode driver. In IIS 5.0, the INETINFO.EXE file was the main Web server process. It will also have limited VPN and Active Directory support.Ĭosmetically, IIS 6.0 looks almost exactly like IIS 5.0, but the entire server architecture has been redesigned. So what’s left out of Web Server? Below is a list of features found in Standard Server but not in Web Server:Īlthough no specific information is available at this time, according to the Microsoft Web site, Web Server will have limited support for Public Key Infrastructure (PKI) encryption, certificate services, and smart cards. Because Microsoft specifically geared Web Server toward hosting Web sites, many of the features found in Standard Server, Enterprise Server, and Datacenter were left out. Generally speaking, the more features a software product has, the greater the chance that one of those features could be exploited to gain unauthorized access to the system. You may wonder what makes Web Server more secure than Standard Server if both use IIS version 6.0. NET Web Server gives companies a less expensive, more secure environment than Standard Server or other editions of Windows. NET, is essentially a watered-down version of Standard Server. NET Web Server, the new Web Server version of Windows. NET Data Center Server replaces Windows 2000 Data Center Server. ![]() NET Enterprise Server replaces Windows 2000 Advanced Server. NET Standard Server replaces Windows 2000 Server.
