Thanks Michael for your quick response. Even with ListFiles it is doing the samething. Below is the log..
What is this IP: 192.168.154.1. Is it the master browser. Also do I need to set any other properties like "Wins' etc. Please let me know.
Also it was timed out when I tried to ping "192.168.154.1" .
Thanks

This shows that the listFiles on smb:// URL did a NetBIOS lookup for the special __MSBROWSE__ name. That's ok. But then 8 computers responded that they were master browsers. That's a little awkward since there's really only supposed to be one master browser on the network and there are "elections" to ensure that this is true.

This exception means that the doConnect method never completed before the connection timeout period. It is difficult to tell if this is incorrect behavior because you set a high responseTimeout value. It would have been better to report what happends if you do not set that value. Better still, just run java -Djcifs.properties=my.prp ListFiles smb://.
My guess is that JCIFS cannot connect to 192.168.154.1 or it is not responding.
