We are runnning NW51 SP7 with BorderManager 3.7, the Server is pretty
healthy Pentium 4 with over 2G of Ram - we are receiving the following
error message at the system console on our Private LAN - NIC detected fifo
underflow error. Once this happens no clients are able to access the
server and it has to be restarted. We have replaced the NIC card and the
same error still occurs.
