ASP.NET State Service

The ASP.NET State Service (aspnet_state) provides support for out-of-process session states for ASP.NET. If this service is stopped, out-of-process requests will not be processed. If this service is disabled, any services that explicitly depend on it will fail to start.

This service is not installed by default on Windows 7 or Windows Server 2008 R2. Once installed, its startup type is Manual.

When the ASP.NET State Service is started in its default configuration, it logs on by using the Network Service account.

This service is available on Windows 7 Home Premium, Windows 7 Professional, Windows 7 Ultimate, and Windows 7 Enterprise in addition to all versions of Windows Server 2008 R2. It is not available on Windows 7 Starter or Windows 7 Home Basic.

This service is not dependent on any other system service, nor is any service dependent on it.

The following table identifies the application protocol, network protocol, and ports used by the ASP.NET State Service:
