Some services are preloaded unexpectedly on an IIS server in Windows

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You install the Windows Server AppFabric feature on an Internet Information Services (IIS) server that is running Windows 8.1, Windows Server 2012 R2, Windows 7 service Pack 1 (SP1), or Windows Server 2008 R2 SP1.
  • You create a website, and then you add multiple applications to the website.
  • These applications are running under different application pools.
  • You enable the auto-start feature for different services in these applications.
  • You deploy a new service to run under the same website. Or, you restart an existing service.
In this scenario, all the services in these applications are preloaded in all the application pools. The expected behavior is that the services are isolated to their specific application pools.

For example, you create a website that is named MySite on an IIS server. MySite includes two applications, which are named App1 and App2. MySite and App1 run in an application pool that is named AppPool1. App2 runs in an application pool that is named AppPool2. In App1, you enable the auto-start feature for a service that is named service_App1. In App2, you enable the auto-start feature for a service that is named service_App2. When you deploy a new service_App3 in application App3, and then run the service in application pool AppPool3, service_App1 and service_App2 are also loaded in the application pool AppPool3. However, only service_App3 should be loaded.

Cause

This issue occurs because of an error in the W3wphost.dll file. This error causes services to be preloaded in multiple application pools after a configuration change.

Windows 8.1 and Windows Server 2012 R2 file information and notes

Important Windows 8.1 hotfixes and Windows Server 2012 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8.1/Windows Server 2012 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.3.960 0.17xxxWindows 8.1 and Windows Server 2012 R2RTMGDR
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 8.1 and for Windows Server 2012 R2" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
