This problem may occur when an antivirus
application is still running during the installation of Windows XP
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.
To resolve this problem, apply hotfix 953979.
