[jcifs] our request can work but it is very slow

Hi,
 
jCIFS authentication works for us.  The password login windows does not pop up.  But it's very slow.  It takes more than 20 secends to get authenticated.  Has anyone seen this problem?  Maybe some network configuration? 
The computer is in the domain, DNS has A record for the computer, Active Directory has the computer and the user.
 
Please help.  thanks.
 
 
I use the Examples/NtlmHttpAuthExample.java and set web.xml:
