set up your switch (if managed) to do port mirroring from the port the PIX is connected to the port your windows machine is plugged in.  Most switches (managed) will allow this. if not, you will have to insert a hub (bad for VoIP and networking in general) on the pix's connection and make sure your pc is also on the hub.

This setup will capture all traffic to the pix on the LAN interface, as well as all traffic from the pix's LAN interface.

If you really want all traffic on a subnet, the port mirror will be different, based on the switch model/make. Pls advise on such.

I do not have physical access to the switch so i do not know which ports are which.  I need a another way to do this that is independant of a switch.

you could try a debug packet on the pix but that would cause so much ovehead it could take the network down -

you would run a syslog server on your windows box and point the logging from the pix to that ip address of your server

logging host x.x.x.x

download a syslog server from cisco...
