I.e., the network adapter on your Windows 2000 PC - the machine running Ethereal - is a Broadcom NetXtreme Gigabit Ethernet adapter? 


But I get all the 'to and from' packets on my PC which is a windows 2000
and Intel 8255x-based Integrated Fast Ethernet. I am on a different network
too.
I.e., you have *another* PC, which has an Intel 8255x-based Ethernet adapter, and on *that* PC you see traffic being sent by that PC, as well as traffic being sent to that PC? 


Do you have any other thoughts to add on why  'source' packets are missing
on 'Broadcom NetXtreme Gigabit Ethernet Driver'.


If:
when you run Ethereal on the PC with the 8255x-based adapter, you see traffic to and from the PC;
when you run Ethereal on the PC with the Broadcom NetXtreme adapter, you see traffic to the PC but not from the PC;
then the problem is probably with the adapter or its driver - it might not be supplying transmitted packets in promiscuous mode. Try capturing with promiscuous mode turned off. If *that* doesn't work, the driver is probably not even supplying them in "all local packets" mode.
