&gt; Hi, Francois, I hope you can help me in this situation. The patch<br>
&gt; attached to bug 31994 [1] (compiled version at [2]) runs fine in most<br>
&gt; testbot machines (tested dozens of times) and my personal XP machine,<br>
&gt; but for some reason it doesn&#39;t work in xppro and w2008s64.<br>
<br>
I have tested this in two Windows XP VMs and indeed, disabling the<br>
firewall fixes the issue. Also I did not see any predefined setting<br>
could be flipped to change this behavior. My understanding is that with<br>
SP3 installed by default the firewall blocks everything except what is<br>
allowed. So by default broadcasts do not get it.<br>
<br>
Adding ws2_32_test.exe as an exception to the Windows firewall also<br>
solves the problem but I don&#39;t think it can be automated which would be<br>
mostly needed for the testbot.<br>
<br>
What&#39;s strange is that Windows 2003 is ok but not Windows 2008<br>
although both are server editions.<br>
<br>
Can the test work with 127.0.0.1 + 127.255.255.255?</blockquote><div><br></div><div>Thanks for the test, so disabling in 2008 solves too or not?
