N/A - KB922582

Today we are announcing the availability of an update that does not address a security vulnerability, but is a high priority for customers in keeping their systems updated. The update addresses the following issue:

You may receive error code 0x80070002 when you try to update a computer running on Microsoft Windows that has a minifilter-based application installed. This error code could occur when updating using any of the following Microsoft tools:

Automatic Updates

Windows Update Web site

Microsoft Update Web site

Inventory Tool for Microsoft Updates (ITMU) for Microsoft Systems Management Server (SMS) 2003

Software Update Services (SUS) 1.0

Windows Server Update Services (WSUS) 2.0

Currently, File Server Resource Manager (FSRM) is the only known minifilter-based application that can cause this behavior and is only available in Windows Server 2003 R2. However, many companies are developing minifilter-based applications that will be available in the near future.

We encourage Windows customers to review and install this update. This update will be offered automatically through Automatic Updates. This update has been designed to install successfully even if a minifilter driver is installed that is preventing other updates from installing. For more information about this issue, including download links for the available non-security update, please review Microsoft Knowledge Base Article 922582.

What is the scope of the advisory?
This advisory clarifies the Microsoft Knowledge Base Article and its associated update. The update does not correct a security vulnerability, but is instead an update for the condition that results in the error code 0x80070002. This error code results when updating a computer, on which a minifilter-based application is installed, by using Automatic Updates, Windows Update, Microsoft Update, Systems Management Server, Software Update Services, or Windows Server Update Services. This update affects the software that is listed in the “Overview” section.

For more information, see Microsoft Knowledge Base Article 922582.

Is this a security vulnerability that requires Microsoft to issue a security update?
No. This issue is not itself a security vulnerability. Rather, this issue affects your computer system’s ability to successfully install security updates. For more information about this issue and how to download the update, see Microsoft Knowledge Base Article 922582.

What causes this issue?
In some scenarios, the error code 0x80070002 can occur if the computer is running a minifilter-based product that uses the Microsoft Filter Manager technology. Filter Manager may return a STATUS_OBJECT_NAME_NOT_FOUND value instead of a STATUS_OBJECT_PATH_NOT_FOUND value. This can cause the issue described at the beginning of this advisory.

The0x80070002 error code can have other causes. For more information about how to determine whether you are affected by this issue, see the next frequently asked question.

How do I know whether this issue affects me?
You may be affected by this issue if your computer returns the error code 0x80070002 when trying to update by using Automatic Updates, Windows Update, Microsoft Update, Systems Management Server, Software Update Services, or Windows Server Update Services. In addition, your computer is running a minifilter-based application.

To determine whether you have a minifilter installed, see Microsoft Knowledge Base Article 922582.

Note We recommend that you install this update even if you do not have any minifilters installed, because we expect increased adoption of minifilter technology very soon. Installing this update will ensure that you will not be affected by this issue even when you install a minifilter-based product in the future.

What is Microsoft Filter Manager? What are minifilters?
Microsoft Filter Manager is a file system filter driver that simplifies the development of third-party filter drivers. A file system filter driver intercepts requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request. Examples of file system filter drivers include anti-virus filters, backup agents, and encryption products. A filter driver developed to the Filter Manager model is called a minifilter. For more information about file system filter drivers, visit the following Microsoft Web page.

Won’t this issue affect the installation of this update?
This update will install correctly even if the computer is already affected by this issue. However, you may be unable to install other updates until you install this update.

This is a security advisory about a non-security update. Isn’t that a contradiction?
Security advisories address security changes that may not require a security bulletin but may still affect customer’s overall security. Security advisories are a way for Microsoft to communicate security-related information to customers about issues that may not be classified as vulnerabilities and may not require a security bulletin, or about issues for which no security bulletin has been released. In this case, we are communicating the availability of an update that affects your ability to perform subsequent updates, including security updates. Therefore, this advisory does not address a specific security vulnerability; rather, it addresses your overall security.
