Introduction Installations Security Enhancement Manageability Enhancements Performance and Scalability New Features Platform Improvements Summary
Microsoft Internet Information Server (IIS) is integrated with the Microsoft Windows NT Server Operating System to provide a Web server for organizations.

Installs in a locked down state Installing 2003 server doesn’t install IIS by default.
Disabling via group policy Administrators can prevent users from installing IIS
on their computers
Command-line tools not accessible to web users
IIS 6.0 command line tools can’t be executed by the web server
Secure Socket Layer (SSL) Improvements Performance
Faster in processing than IIS 5.0 Remotable Certification Object.
Allow customer to manage accounts remotely. Unlike IIS 5.0
Selectable Cryptographic Service Provider Easy to select Crypto API Provider to
accelerate performance. Unlike IIS 5.0
XML MetabaseThe metabase configuration for IIS 4.0 and IIS 5.0 was stored in a proprietary binary file and was not easily readable or editable. IIS 6.0 replaces the proprietary binary file, called MetaBase.bin, with plain text XML formatted files. Which incorporates rich functionality, such as inheritance, data typing, change notification, and security.
Automatic configuration versioning◦ The Metabase feature automatically keeps track
of changes. Edit-While-Running Feature
◦ IIS 6.0 gives the administrators to change the server configuration while the server is running, through direct editing to the Metabase.xml file.
Server Independent backup and restore◦ With a user supplied password, administrators
and developers are able to create server-independent backups.
XML Metabase
New Web-based Administration Console IIS 6.0 includes a new Web-based
administration console called the Remote Administration Tool. Using the Remote Administration Tool, administrators are able to remotely administer IIS 6.0 across the Internet or the intranet through a Web browser.
HTTP. Sys- New Kernel-Mode Driver Caching Policy & Thread Management Web Gardens Persisted ASP Template Cache Large Memory Support for x86.0 Site Scalability
A single point of contact for all incoming HTTP requests.
High performance connectivity for HTTP server application
Driver sits atop TCP/IP and Receive all requests from the IP/port Responsible for overall connection
management, bandwidth, throttling, and web server logging.
IIS 6.0 has heuristics built in that use to:◦Determine the cacheable hot-set of an
application or set of sites◦Determine which items should be cached
on the basis of the distribution of requests that a particular application receives.
◦Makes better use of resources on the server
◦Makes decisions to increase/reduce concurrency on the basis-efficient in using concurrency.
Web Gardens:◦ An application pool has multiple processes serving
the requests routed to the pool.◦ Possible to configure the worker processes in a
web garden.◦ Increase scalability
Large Memory Support for x86.0◦ For workload have a great deal of cached data.◦ Can configure to cache up to 64 gigabytes (BG).
Persisted ASP Template Cache◦ Templates are store on disk that work more
efficiency and faster response.
Improved the way internal resources are used
Many more sites can be hosted on a single IIS6.0 server
Larger number of worker processes that can be concurrently active
Quicker startup/shutdown of the server when hosting sites.
Capable of having thousands of isolated applications configured – each run with its own application pool worker process.
ASP.Net and ISS6.0 integration Buffer and handle send Internal redirection Caching dynamic content Worker process recycling ISAPI support for custom errors Improves ISAPI Unicode support New COM+ services in ASP
ASP.Net and IIS 6.0 Integration ◦ Developer have high levels of functionality
Rapid application development Wide variety of languages to choose from
◦ Is a result of enhanced process model integration in IIS 6.0 that support XML, SOAP, and IPv6.
Buffer and Handle Send (VectorSend)◦ Server support function for ISAPIs◦ Put together a list of buffers and file
handles to send in order◦ This frees the ISAPI from doing any of
buffer construction or multiple write clients.
Execute URL◦ Allow an ISAPI extension to easily redirect a
request to another URL.◦ Replace almost all read raw data filters◦ Allow ISAPI extension to process the request
entity body and pass it to a child request.
Global Interceptors◦ Implement ISAPI request interceptors: intercept,
change, redirect, or deny incoming HTTP request from specific URL space.
New Features:
Caching of Dynamic Content◦ Implementation of Kernel-mode for dynamic
content◦ Benefit many customers have programmatically
created content that doesn’t change.
Worker process recycling◦ IIS 6.0 support function called
HSE_REQ_REPORT_UNHEALTHY that allow ISAPI extension call into ISS 6.0 worker process to request that worker process be recycled.
◦ Allow developer to pass in a string representing the reason.
ISAPI Support for Custom Errors◦ Developer no longer need to generate their own
error.◦ Instead, they can plug into the custom error support
built into IIS 6.0 through a new server support function called HSE_REQ_SEND_CUSTOM_ERROR.
Improved ISAPI Unicode Support◦ Important in a global economy◦ Be able to get variables in Unicode and adds two
new server support functions
New COM+ Services in ASP -Separated the COM+ services from component and allow ASP application to use a set of COM+ services in IIS 6.0
Fusion Support -allow an ASP application to use specified version of a system runtime DLL or classic COM component.
Partition Support – define a different configuration of a single COM+ application for different users. (security and version)
Tracker Support – allow administrators to monitor what code is running within the ASP.
Apartment Model Selection – allow developer to determine which threading model to use when executing the pages in an application.
64-bit Support-The complete Windows Server 2003 family code base is compiled for 32-bit and 64-bit platforms.
IPv6.0 Support-is the next generation IP protocol
for the Internet. Logging Improvements
◦ UTF-8 Logging Support-support IIS 6.0 writing log files
◦ Binary Logging-allows multiple sites to write to a single log file in a binary, non-formatted manner
◦ Logging of HTTP Substatus Codes-helpful in debugging or troubleshooting
File Transfer Protocol (FTP)◦ FTP User Isolation-easy availability and wide
adoption for customers to upload the Web content ◦ Configurable PASV Port Range-can reduce the
attack surface of IIS 6.0 FTP servers by allowing administrators to have more granular control over the port ranges that are exposed over the Internet.
Improved Patch Management◦ No service interruption while installing
patches-which means an administrator can easily install most IIS 6.0 hot fixes and most new worker process DLLs without any interruption of service.
