as Home uses simple file sharing by default. I never used simple file sharing. What you might do is uncheck the box and and this allows you to set up sharing and permissions yourself. I'm thinking that the box is unavailable because sharing is, in fact, already turned on. Turn it off and, in this way, you can have full control of the sharing process. Good luck.
Have XP SP3 with 1.2M memory and plenty of hard disk space. I have tried in the past and given up but this time I'd like to overcome whatever problem I have. Every article says it's so simple. I have a Verizon wireless router, wireless system that I use for at time up to 3 computers. Each has it's separate name and I think the workgroup name is WORKGROUP. Real original. Anyway the SFS box is checked and enabled in Folder's Options. But when I right click on a Folder and go to Properties, then Sharing, the area where you would check SHARE THIS FOLDER WITH OTHER NETWORK USERS it's not available to be checked. The boxes are unchecked and you cannot check them. I have tried several things including turning off the firewall with no success. I am supposed to be the administrator since that's the way I set it up. Does anyone have any suggestions for this nagging problem? Thanks so much in advance! jack
