To disable auto login network share folders

XP has the same sharing/permissions options as vista but they are disabled by default.

Open up a folder and browse to ToolsFolder Options and click the View tab, scroll down until
you find Use Simple File Sharing -> it’s at the bottom, and remove the tick. Hit apply and right click a folder.
Your options should now be visible.

• 1- Right click on the shared folder and select properties.
• 2-From sharing tab select permissions.
• 3-Remove everyone
• 4-Add your user name and select permission type "read only" or "full control".

Now only your username have permissions to access this folder.

Hope that’s what you were after
