OK - Just to recap.
I have two seperate windows networks and an UBUNTU workstation that has two network cards in so it can see both networks.
On the UBUNTU machine i have mounted a share that exists on Windows network 'A' and I have made an entry in my etc/fstab file to ensure that the share is resored on boot up.
The share can be accessed on the UBUNTO machine and can read, write create, and delete files with no problem - All ok so far :-)
The mounted Share apears as a folder: mnt/winshare
I have shared that out (right click in Nautilus) in order to make it visable to users on Windows Network 'B' - I put a tick in the box to allow others to create and delete files in the folder, however from a machine on windows network 'B' I can connect to the UBUNTU share and can see all the files.
I can open files but i cannot save any edits, create files or folders etc - the access is only read only.
I need it to be read write!
Can anyone help me achieve this?
