I have a Windows 2000 Server that runs Lotus Notes for the entire agency. We are going to web mail and the adminstrators have scanned my server for possible open ports before opening us up for web mail. They say they have found port 2473 to be open and they want it closed. We have traced the port to Aker which is supposedly some security company but either way if this is something illegitimate or not is there a way to disable this port? Or can someone tell me exactly what the port is and whether every server has this or is it something I can get rid of. Thanks.

Right, this is part of some Aker software, since it's your email server, it might be their Secure Mail Gateway. If you want to see their site:

http://www.aker.com.br/index.php?pag_cod=1&ling=en_us

But if you uninstall the software, or disable the Aker service that is running on that box, it will no longer be listening on that port.

programers who create applications, creates the API that opens up ports that the application needs to function. Further, some ports are necessary to be open for services that run on W2K server to be functional. closing ports on an external interface is done by a firewall program that effectively closes all ports until you explicitly allow traffic [via rules]. Baring having no firewall you disable the service that uses that port or uninstall the program that uses that port that is open and listening. A firewall though is the best protection.

to view open ports at a command prompt type netstat -a to view incoming and outgoing traffic at a command prompt type netstat -e for the NIC that is the external interface.
