Problem solved:
'rmmod ipchains' was the magic word.
(I still don't understand anything

)
Thanks for the help.
I wanted to connect my linux box and window so that they can share files.
I was hoping it was a simple matter of plug and play.
(a newbie's dream

)
So far I have assigned ip to both boxes.
And tried to ftp linux from windows and failed.
Here is weird part.
I could ping linux from window but not the other way.
Any help would be appreciated.
