There is no way to randomly open ports - something has to be listening there for it to be open. You would use the command line to start a service that will open the port.
Net Start xxxxxxx would open ports if there is a service named xxxxxxx in the registry or simply typing the program name of a program that listens on a port such as NetCat with the appropriate switches would open a port.
Other than that you are out of luck. The only reason a port is open is because an app is sat behind it listening for communications with the port. Otherwise nothing can reply to the communication and the port would be determined to be closed.
[Edit] Ooops.... I gotta learn to read...... "close open ports"......
Net Stop xxxxxxxx wil shut down the service that has the port open and you can use the kill app that comes off the resource kit I beleive to kill other app/processes.

Yeah, because it uses much of the recources of your system and specially RAM. Well personally i find it the best in comparison to Sygate Firewall. I also have heard of Tiny Firewall and i have heard that it is very good...

Yes you can manually close ports.
In the advanced LAN settings there should be a options tab, here you can close ports manually.

Correction. That is filtering a port. The program is still listening for connections on that port, however in most cases data will simply never get there.
Also, the TCP/IP filtering only stops incoming connections. If you have some kind of spyware sending info out that port, the built-in filtering will do squat.
Closing a port = terminating the listening application
Filtering a port = blocking it at a firewall level

I realize u're running Win2K, but here's a link to shut some services down in XP.
There's quite a few services the same.

In th lan advanced settings you can only permit a port. But you first have to disable all, then permit the ones you want, one by one. This gets involving.
