You install Microsoft Security Bulletin MS04-031 on a Microsoft Windows XP Professional-based or Microsoft Windows 2000 Professional-based client that is running Windows Internet Name Service (WINS). If the client uses the Clipboard Viewer program (Clipbrd.exe) or any other Network Dynamic Data Exchange (NetDDE)-based program, the number of WINS transaction log files on the WINS server greatly increases. Additionally, these log files occupy lots of disk space.

Note The WINS transaction, or J<n>, log files are located in the %systemroot%\System32\Wins folder. %systemroot% is the folder where you installed Microsoft Windows.

If you use the Network Monitor utility to capture a network trace, the network trace shows excessive registration and de-registration traffic for the NetDDE service on WINS clients. The WINS clients register and unregister the NetDDE service with the WINS server several hundred times per second. This activity loads down the WINS server.

This problem occurs because of a code defect in the NetDDE service on WINS clients. This defect is introduced with Security Bulletin MS04-031.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Back to the top

The following is an example of the name registration and of the name release that are displayed when you use the Network Monitor utility:

NBT: NS: Registration req. for NETBIOSNAME <1F>
NBT: NS: Registration (Node Status) resp. for NETBIOSNAME <1F>, Success, Owner Addr. 10.10.10.10
NBT: NS: Release req. for NETBIOSNAME <1F>
NBT: NS: Release (Node Status) resp. for NETBIOSNAME <1F>, Success

All NetBIOS names are 16 characters in length. A NetBIOS suffix is the 16th character in the 16-character NetBIOS name. The NetBIOS suffix is used by Microsoft networking software to identify functionality that is installed on the registered device. 1F is the unique NetBIOS suffix that is used by the NetDDE service.
