Using Nmap from a remote machine should I found ports 593, 1356, 1420, 2030, 10000.  Do I  have to worry about these open ports on my XP sp2 machine?

Both TCP and UDP ports 539 appear to be used for software called "Apertus Tech Load Determination" see:

http://www.auditmypc.com/port/udp-port-539.asp

http://www.auditmypc.com/port/tcp-port-539.asp

The other ports are dynamic ports (i.e. they are ports higher than 1024) and are therefore ports used  by windows for outgoing traffic.

You can use a GUI application like TCPView:

http://www.sysinternals.com/Utilities/TcpView.html

to determine which ports are being used by which process.

Hope this helps.

When I say dynamic ports are used for outgoing connections, I should really qualify this by saying "generally used for outgoing traffic" as applications can use ports higher than 1024 for server/inbound connection types.

Port 10000 may possibly be a trojan:

http://www.auditmypc.com/port/tcp-port-10000.asp

1420 may be used by a legitmate application or may be dynamic.

As I say above you should check with TCPView to see what may be using these ports.

Let us know if you need help with the results.
