this is an fport on the box:

i have now mapped port 40019 to the DU Update service. the thing that is worrying me is that the ports 1002, 1720, 47624 do not show up in the fport. does anyone know off a good tool so that i can check exactly what protocol is running on a port?

Wassup:
Port 1720: H323 Call Setup:- Used by Netmeeting, video conferencing, CUSeeme uses it. It seems to negotiate a TCP port for H232 protocol, see here
Port 1002: ILS, (Internet Locator Service, the user directory) which is also used by Netmeeting.
Port 47624: Gamevoice?
They all seem to be associated with audio/video stuff. Got netmeeting or anything else going on that box?

1026 is task scheduler. Perfectly normal.
If you want to see what the generic svchost processes are associated with, install the tool pack from the W2K CD. The tool you want to use is called tlist. Trust me, you'll keep tlist handy once you use it.
