Symptoms

Consider the following scenario:

  • You have a server that is running Windows Server 2008.

  • You have Internet Information Services (IIS) 7.0 installed on the server.

In this scenario, the Svchost.exe process of Windows Process Activation Service (WAS) stops running unexpectedly.

Because the World Wide Web Publishing Service (W3SVC) depends on WAS, these services and your web application stop. Additionally, the following events are logged in the Application and System event logs:

Log Name: Application
Source: Application Error

Event ID: 1000
Level: Error
Description:
Faulting application name: svchost.exe_WAS, version: 6.0.6001.18000, time stamp: 0x47919291
Faulting module name: nativerd.dll, version: 7.0.6002.18139, time stamp: 0x4af812b4

Faulting application start time: 0x01cebeec8563f730
Faulting application path: %11
Faulting module path: %12
Report Id: %13Log Name: System
Source: Service Control Manager

Event ID: 7034
Level: Error
Description:
The World Wide Web Publishing Service service terminated unexpectedly. It has done this 1 time(s). Note This problem does not occur on a server that is running Windows Server 2008 R2 and has IIS 7.5 installed.

Cause

When this problem occurs, the Windows Process Activation Service refers to the null pointer during configuration changes. This causes the Svchost.exe process to crash and the websites to restart.

The English (United States) version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.

Windows Server 2008 file information and notes

Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" 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, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table. The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    LDR

  • GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxx version number.

  • 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 Server 2008" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely 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.
