Here is the instruction to see if your inbound and outbound is accepting by firewall,this is only for windows vista,perhaps can go to other windows,but i am not sure,cause i know you have it,so follow the way i know,even it has another way to go.

1-START
2-HELP AND SUPPORT,click on it and will open a small screen and type ADMINISTRATIVE TOOL on search bar,then will say WHAT ARE ADMINISTRATIVE TOOL,click on it,then click where says Click To Open Administrative Tool,it will open another screen and will show few options to choice,double click where says WINDOWS FIREWALL WITH ADVANCED SECURITY,a screen opens and from there you will see DOMAIN PROFILE,PRIVATE PROFILE AND PUBLIC PROFILE,click your profile,private or public,what ever you have and then you see the inbound and outbound,it will show what you want to do,block or allow,just click ALLOW,your profile needs to have all green check marks ok,hope this helps you.
