We are using network segmentation across vlans as a security control.  I have a firewall between the vlans but its completely open right now.  I'd like to configure the firewall to drop all unsolicited traffic between the two networks but I can't seem to find a good resource detailing the ports used to communicate between Win7 and SBS2011 Standard for default roles (exchange, sharepoint, active directory, etc).  If anyone has a nice spreadsheet that has this information at a glance it would be greatly appreciated!
