Also, check out this great site:
http://www.networksorcery.com/enp/protocol/ip/ports00000.htm
It has a listing of all of the well-known ports.
Port 137 is NETBIOS.

The only thing that I'm familiar with that the 169.x.x.x range is used
for is the auto-config in MSFT machines that can't get a DHCP-assigned
address.
