getting linux in network neighbourhood

I configured samba in a linux machine. From samba i get the smb prompt and can browse any other machine on the network. But from the windows machine i can see the samba server in the network neighbourhood but can’t go any further. I created a publicdirectory under home as writeable=yes in the linux box but when trying to access, it says, there is a network error. Even i get the http service from the linux (apache) by typing the http:// in explorer address bar of any windows machine.
What could be wrong?
