Mcafee Internet Security Firewall 2011 blocks file sharing


My Mcafee firewall is blocking file sharing. I have setup Mcafee Internet Security 2011 on Win 7 system and opened up ports TCP/UDP 135-139, 445. I have also added my network as Home and Trusted the Home network. But I am unable to access the shares on my LAN. When I turn off the firewall, I can access shares without any problem.

Please help.
