The is perhaps connected to a different problem with the CEICW wizard I have listed separately and simultaneously in the SBS zone. Perhaps I shouldn't have tried to split them. In any case, since tinkering with some permissions in my main file sharing folder(I thought I increased them) I now can't a see some files and folders from a user account with administrative privileges from one of the client computers I can use the same account to gain access to the same material which I can't access using network places by using remote desktop. Same client computer.
I have given full control for the account under both sharing and security.
