    After I capture all of the network packets, I found the reason why the
windows 2000 always popup the authentication box when I run any printing jog
or configuration.
    It's a Microsoft BUG, not the samba. The default printing method of
windows 2000 is IPP. It will send the IPP request while you print a print job
or configure the printer in the control panel. It doesn't care what the
current action/printer is.
    My problem is due to other engineer in my office ever configred an IPP
printer in the windows 2000. So if my Samba Server configured the same IP
address as the previous IPP printer, windows 2000 will appear the popup box.
Because I found that the windows 2000 always send ARP requests to the specific
IP. Now I solve the problem, just remove the unnecessary part in the windows
2000.
    If it took your time to investigate this problem. I am sorry. This is not
the Samba's problem. But if you met the same situation, you can check your
windows 2000's printer settings. Thanks.
