SYMPTOMS

After you install Windows XP Service Pack 3 (SP3), Device Manager may not show any devices, and Network Connections may not show any network connections.

This problem may occur when an antivirus application is still running during the installation of Windows XP SP3.

CAUSE

This problem occurs when the Fixccs.exe process is called during the Windows XP SP3 installation. This process creates some intermediate registry subkeys, and it later deletes these subkeys. In some cases, some antivirus applications may not let the Fixccs.exe process delete these intermediate registry subkeys.

When this problem occurs, certain applications, such as Device Manager and Network Connections, may be unable to enumerate the device or connection instances. These applications will report a blank status, even though devices and connections still function as expected.

RESOLUTION

To resolve this problem, apply hotfix 953979. For more information about hotfix 953979, click the following article number to view the article in the Microsoft Knowledge Base:
