Connection being aborted by software on host machine.

I recently decided I wanted to make a Minecraft server, so I went through the whole Hamachi thing first and well, it sucked, so I switched to the port forwarding method. It was much simpler, and my friends could join much easier. Then, I decided to make it a bukkit server which really wasn't that hard. It seemed to be working fine for me, until I tested trying to join it from my laptop. I keep getting an error that says "Internal Exception: java.io.IOException: An established connection was aborted by the software on your host machine". My first thought was, "this must be a firewall or security system issue", and a few google searches supported my theory. The thing is, I thought I had already allowed the Minecraft server to go through my port 25565. I assumed then that Bukkit must be using a different program or something that I have not allowed through my firewall.

What I need answered is this:
- Am I correct about my security system blocking my connection
- What program/files/.exe would I need to add to my firewall to allow my connection to be established.

And here are my specs:
OS: Vista Business 32 bit
- No wrappers

- Craftbukkit ​

1.7.9-R0.2 beta​

-I use run.bat to run the server
-I'm running the Essentials, as well as Bookrules and Stickylocks
-I told you the error message I get (when I try to join from my laptop) in the paragraph above.


I'll keep working, if you can help please do! Thanks.
