What is the default firewall policy of a Windows 7 box that is a member of a Windows 2003 level domain?

We have far too many hosts blocking SMB on 445 and struggle to understand how so many have been configured to block the traffic. (About 42% blocks, the rest passes the traffic fine.)

There is no way that we "manually" configured the firewall on all those Windows 7 boxes to accept SMB on 445 so we assumed the default behavior was allow 445 when File Sharing is turned on, but that does not appear to be the case.

We do not/did not have a GPO policy to configure the firewalls to block or allow!

How can there be such a discrepancy?
