QuestionUDP ports 500 and 4500 are busy? Pin

My application must work on a remote computer with ports 500 and
4500 on UDP-protocol, but it doesn't work.
I tried to test these ports by this udp-server.
http://www.codeproject.com/Articles/11740/A-simple-UDP-time-server-and-client-for-beginners

Antivirus is switched off, Firewall too.

When I start udp-server as "timeserver 500" or as "timeserver 4500"
I get message: "Could not bind name to socket".
But with other ports it works. Why? (In the source code I do not
see any restrictions for port-numbers.)

On my local home computer - the same behavior!
Can anyone explain this?
