[jcifs] Problem connecting with domain controller

we found out that this problem does not exist anymore when using jcifs V1.2.8
(the version used when reporting the error was 1.2.3).

As V1.2.3 works in our test environment I have two question that I would like
to ask you:
1.) The Port 0-SYN packet does not seem to be sent anymore when using V1.2.8.
Was this a bug or just some kind of adjustment for problems of this or another
2.) When searching for this phenomenon in the web I found several sites that
contain recommendations to close Port 0 in the firewall. Do you think it is 
likely that this could cause the problem in our case?

Many thanks for your help in advance!

Best regards,
