Edit the file
/usr/sbin/sambastart
remove everything out of it except the stop and start command.
open a root window and execute the command
Code:
#smbpasswd -a <username>
Do that for each user you want to add, the user must also be a user on that machine
you may add a password or no password to the user name "nobody"

Edit the file
/etc/samba/smb.conf
Add a section for the shared path
Code:
[scratch]
  comment = Marty's Scratch directory
  writeable = yes
  path = /scratch
  public = yes
The above is just a sample, make sure the path is shared.
Run samba
You should now see that machine from any windows machine.
