[jcifs] 1.2.4 NameQueryRequest fails in OC4J on AIX (0.8.3 works)

[Oliver Schoett]

I cannot upgrade the NtlmHttpFilter from jCIFS 0.8.3 to jCIFS 1.2.4 in
OC4J 9.0.4 on AIX, because the NameQueryRequest fails.  Here is the
error log of 1.2.4 (IP addresses and domain names modified):

In contrast, the NameQueryRequest of 0.8.3 works (and we use it
successfully for NTLM HTTP auth):

The only difference I can see in the query packets ist that the
non-working packet has isBroadcast=false, whereas the working packet
has isBroadcast=true.  Could this be the cause of the different
responses received?
