Interesting. There should be a little hand on the folder that you want to share. Possibly, you used the wizard to make it shareable originally. What you will want to do is - using windows explorer, click on the folder, then right click on it and after choosing Sharing and Security remove its shareability. The hand should disappear. Then, right click on the folder, choose Sharing and Security. Sometimes a window comes up and warns you about Sharing and that you should use the wizard - don't - just choose the selection that lets you make it shareable. After choosing that a window will pop up with three tabs. The middle one should be selected. You can read in the middle of the window, that you can click on making it shareable, give it a password, and also allow users to modify it. Then, you will need to go to each computer that accesses that folder and clicking on it will provide a dialogue window where the userid and password has to be supplied. When you do so correctly, it will ask you if you want it to remember this setting. Tell it yes.
