Hi Torben

I would like to thank you for sparing your valuable time to solve my problem. I could not give my immediate reply as I was out this weekend, so excuse me. 

Coming to the issue,

As you suggested I changed to version 1.2.17

I tried all the 3 steps that you suggested and the result is as under

1. those who could not connect through laptop are able to connect through regular pc using their username and password. 

2.when I disabled auto logon feature in IE settings, its prompting for username and password. Also I could able to reach server from their system, i.e. I could open tomcat admin console of server from their system. 

3.i find a little difference in the output of 'tracert <server>' on machines those accessing and those not accessing. Even then I could reach server machine from both systems ( as I could reach tomcat admin console from both systems ) so I don't think it's a problem. 

To tell you, when I commented out the code that is accessing the windows login user's name, I am able to hit the application from all systems.

You also suggested to try out Ethereal, we don't know how to use it. 

Here is the extra info you asked that might help to trace the problem.

-Windows version over which tomcat running : windows server 2003

-windows version on laptops : windows XP

As I told you before there are some laptops with windows XP over which app is accessible. 

-IE version on all systems are 6.0

We did not installed any servicepacks anywhere.

I know that I am troubling you too much, but hope you understood my situation and help regarding this.

Thanks and regards

Hi Ashok

I meant that the library in the meantime is up to version 1.2.17 and you are still using 1.1.11...

When connecting from the laptops -- do you always only get a "SmbComTreeDisconnect" message?

I don't think the problem lies with JCIFS -- then it wouldn't work for the regular users either. 

Some things to try out:

1) Have one of the laptop users logon a regular PC, and see if they can connect to the application.

   This is to see if it is something with the account.

2) Try to disable the autologon feature in Internet Explorer 
(Tools->Internet Options->Security->Custom Level -- at the bottom locate "Logon" and set to "Prompt for username and password")

   This is to see if the users have connected to the server that hosts Tomcat earlier and maybe checked of "Remember password". 

3) Make a "tracert <server>" on a commandline on both regular PC and laptop

   To see if the network paths are different (firewalls/routers/proxies)

If this doesn't give any clues I would still try to run Ethereal at the server to see what the difference is between the communication between a regular PC and a laptop... 

Some other useful info you could provide:

- Windows version (incl. ServicePacks) of the server running Tomcat

- Windows version (incl. SPs) of the domain controller

- Windows version (incl. SPs) on laptops 

- Windows version (incl. SPs) on regular PC's.

- Internet Explorer versions (incl. SPs) on laptop

- Internet Explorer versions (incl. SPs) on regular PC's.
