Essential IIS Services and Processes

|

Windows services and processes are other areas where Windows and IIS are tightly integrated. Table 3-3 provides a summary of key services that IIS uses or depends on. Note that the services available on a particular IIS server depend on its configuration. Still, this is the core set of services that you'll find on most IIS servers.

Dependencies

Application Host Helper Service

Apphostsvc

Provides configuration history services and app pool account mapping for file and directory access locking.

Automatic

Local System

Restart the service

None

ASP.NET State Service

aspnet_state

Provides support for out-of-process session state management for ASP.NET. Out-of-process state management ensures that the session state is preserved when an application's worker process is recycled. IIS uses this service only when you set the Session State mode to State Server or SQL Server. Otherwise, IIS does not use this service.

Manual

Network Service

Restart the service

None

FTP Publishing Service

MSFTP-SVC

Provides services for transferring files by using FTP. If the server isn't configured as an FTP server, the server doesn't need to run this service. In a standard installation of IIS 7.0, when you install FTP, this service is, by default, configured for manual startup only.

IIS Admin Service

IIS Admin Service

IISAD-MIN

Allows administration of IIS 6.0–related features, including the metabase. If the server doesn't need backward compatibility, the server doesn't need to run this service.

Automatic

Local System

Run iisreset.exe

HTTP, RPC, Security Accounts Manager

Web Management Service

WMSVC

Enables remote and delegated management of IIS using IIS Manager. If a server is locked down so it can be accessed locally only, the server doesn't need to run this service.

Automatic

Local Service

Restart the service

HTTP

Windows Process Activation Service

WAS

Provides essential features for messaging applications and the Microsoft .NET Framework, including process activation, resource management, and health management. This service is essential for IIS.

Automatic

Local System

HTTP, Windows Process Activation Service


As the table shows, the World Wide Web Publishing Service and Windows Process Activation Service provide the essential services for IIS 7.0. Management of the Web service and Web applications is internalized. The Web Administration Service component of the Web Service Host is used to manage the service itself. Worker processes are used to control applications, and no Internet Server Application Programming Interface (ISAPI) applications run within the IIS process context.
