Find out what Windows 7 Firewall is blocking to prevent Client / Server communication

Try to shutdown the firewall,
then use the "netstat" command to see which ports its using,
then open them in the firewall.

EDIT:
another option would be to use sysinternal's TCPview

    I have a client / server application and both client and server are on windows 7. If I disable the firewall on the pc acting as a server everything works great but if I enable it back the client is not able to connect anymore. I'd like to find out what I have to allow on windows firewall settings but I have no clues about what's being blocked and why. Also enabling the whole traffic coming and going to a certain ip would be acceptable as a solution.

    Thanks!

      What is the client/server application? Is it something you bought, or someone wrote custom?

      Someone wrote custom... That's my problem. I don't know what are the process / services involved... And windows 7 firewall won't give any kind of feedback after blocking :/
