Network Monitor stops capturing packets during heavy network traffic

Network Monitor may stop capturing packets when it monitors a Microsoft Windows Server 2003-based computer during a period of heavy network traffic. In this scenario, the # Frames value remains constant in the Captured Statistics pane of Network Monitor.

This problem occurs because of a problem in the Network Monitor driver code.
