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

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


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 the Network Connections item in Control Panel, may be unable to enumerate the device or the connection instances. These applications will report a blank status even though devices and connections still function as expected.
