Simple File Sharing disables self

We have a Novell Netware 6.5 environment, Windows XP (mainly SP1, some SP2). We are using the Novell Client 4.90 SP2. We would prefer to use Simple File Sharing (SFS) to allow our users to share data and printers (we are moving to iFolder, iPrint in the near future). We have found that when this “enabled”, you have to re-enable it every restart/login. If you don’t re-do it every time, then it doesn’t work. When you try access the machine from another PC it says – “Login Failure: the user has been granted the requested logon type at this computer.” I have resorted to using the classsic file sharing, but this means creating a user account for everyone that wants to access your machine/their machine on the PCs. This isn’t very viable. Has anyone else found this?
