I have tested this in two Windows XP VMs and indeed, disabling the 
firewall fixes the issue. Also I did not see any predefined setting 
could be flipped to change this behavior. My understanding is that with 
SP3 installed by default the firewall blocks everything except what is 
allowed. So by default broadcasts do not get it.

Adding ws2_32_test.exe as an exception to the Windows firewall also 
solves the problem but I don't think it can be automated which would be 
mostly needed for the testbot.

What's strange is that Windows 2003 is ok but not Windows 2008 
although both are server editions.

Can the test work with 127.0.0.1 + 127.255.255.255?
