[jcifs] Problem - Drive share done by Default on Server

[Swati]

Hi,

I can successfully check the shared resources shared by the server running with 
SMB share. This testing is done with windows 2000 machine.

My problem is when I try to check the shared resources from the server, it 
shows all shared resources including all the drives present on that server as a 
shared one. Whereas when i checked on the server, the drives are not explicitly 
shared. Then why am i able to get those drives as shared one? Is it because of 
the Windows Network setup? 

I want to access only the explicitly shared resources from the server.
Is there any standard way to achieve this?

Thanks in advance,
Swati
