Brian, Thanks for the information. I stopped the IPSec service but still get the same information. Not sure what service would be controlling h.323 though I am looking. -cfd -----Original Message----- From: Brian F.

Clifford, Port 1120 is used by Win2k for IPSec, this is the most likely cause for the port activity you are seeing.

Can anybody give me some insight what the heck is using port 1120 and 1900?
From what I've read 1900 is UPnP on XP and ME but my machine
(xxx.xxx.xxx.165) is a 2K server and the recipient address (xxx.xxx.xxx.161) is a Cisco router. Looking through the Internet Asignment Authority port assignments page (http://www.iana.org/assignments/port-numbers) it lists port 1900 as SSDP (Simple Service Discovery Protocol) and 1120 isn't even listed. I get these approximately every 30 seconds.
