Step 4: Disable Simple File Sharing
Simple File Sharing allows users to share folders without a password and may allow malicious attackers to read or write files from your shared folders.
Windows XP Professional only allows you to disable Simple File Sharing and
require a userid and password for shared folder access. To disable Simple File Sharing follow these steps:
- Click Start > Control Panel.
- Double-click Folder Options.

- Select the View tab.
- Scroll down in the list and uncheck Use simple file sharing
(Recommended).
- Click OK.

Set a Password for File Sharing
If you are going to permit file sharing from your computer, you should always set permissions for the folder being shared. Before sharing a folder, keep these tips in mind:
- Sharing entire drives can be dangerous, especially if you are sharing the C: drive.
- Do not make a network share writable by others.
- It is never a good idea to give Full Control to your share.
