[jcifs] Authentication failed against a Windows XP server

[Palak]

Hi,

I just started to use jCifs to access remote servers and retrieve files. I 
succeeded to authenticate against Windows 2003 and later Windows, and crawl 
data. 
However, i fail to authenticate with Windows XP. I checked the packets 
exchange, and it's like as soon as i get connected, instead of using the user 
name and password i provided, the system tries to connect as a guest.

Do you have any explanation on that?

Thanks.
Palak.
