Restricting guest access

Unauthorised users can access your Win2K PC by specifying Guest in the login window. To disable the Guest account, open Users and Passwords from the Control Panel. Click on the Advanced button twice to display the Local Users and Groups window. In the left pane, double-click on Users. Here, right-click on Guest and choose Properties. Once there, disable all options by clicking in the check box against each.

Monitoring shared folders

If you don't set the right permissions for your shared folders, unwanted users might gain access to them. Unlike in Windows 95 or 98, Windows 2000 allows you to close files that have been opened by unauthorised users-without unsharing the folders that contain them. To do this, right-click on the My Computer icon and choose Manage. In the window that opens, click on Shared Folders and then on Open Files. In the right pane, you can see all the files on your machine that have been opened by various users. Simply right-click on the file that you want to close, and click Close Open File.
