Leopard folder sharing problem

Ok this was working, but I tried to enable SMB for a Windows machine and now it doesn't.

I have enabled "File Sharing" in "Sharing" prefs on my iMac, and granted "Read & Write" access to a "Sharing Only" account called MacBook on multiple folders. E.g. Desktop, Downloads, Documents, Music, Movies, Pictures. Only AFP is enabled in "Options".

On my MacBook logged in as MacBook I mount each of the shared folders within finder. Like I say this used to work, but now after connecting and authenticating successfully I don't see any files or folders within the mounts.

Any ideas?

 

Its even worse. I can't rename certain folders or files that were previously shared ON MY IMAC. The permissions are well and truly shafted.. Permission denied apparently..
