SYMPTOMS
On a Microsoft Windows Server 2003 x64 Edition-based computer, you discover that TCP/IP activities are unavailable. This problem occurs if the following conditions are true:
 * The computer has more than 4 gigabytes (GB) of memory installed.
 * The TCP/IP activities depend on an IEEE 1394 network adapter.

When this problem occurs, TCP/IP communications do not work as expected. For example, the computer does not respond to ping commands. Additionally, shared files and shared printers are not available on the network.

Note TCP/IP activities work correctly over a network adapter that is not based on IEEE 1394 technology.



CAUSE
This problem occurs because the Ohci1394.sys driver cannot flush the direct memory access (DMA) buffer.
