Default Need information on ports

I'm working on sniffing out the ports on a network I practice on. For fun we test with net send in a batch file to see what ports it can go through. We have noticed some of the net send messages don't make it across the room, only a few people randomly receive them. Those few blocked off there port and now no one can see the messages. Our research is to find

1) How to find all the ports open on a network
2) how to use those ports to an advantage (Possibly send a net send through them)
3) How are we able to change the port data is sent using the command prompt, if possible?

If anyone can help with this I would greatly appreciate it.
Note: This is all for the purpose of research in a class I'm in, networking+.
