[jcifs] Network name resolve time

[yankings]

Dear All,

Thanks for both of you!  

I tried to convert my testing program to use DNS by adding the domain suffix
but no improvement on the logon process (still needs 2x seconds to logon).

I found that if the following properties set, the performance will be the
same as ver 1.1.11.  I will go for this workaround before i figure out what
happen to those twenties seconds,  

          Config.setProperty( "jcifs.netbios.scope","test_scope_id");
          Config.setProperty( "jcifs.resolveOrder", "LMHOSTS" );
