Dear friends,
Im working in an office as a officer, for my department I want to share a folder so I have shared my folder, if any body is aceessing my PC in network it is asking guest password in this case the guest is inactive , but I want to enter the user name and password, this is my problem, I'm not using any server.

Highlight the shared folder and right click and select Sharing and Security. You can then apply a password to access the folder.
