Mapping network drives allows you share folders on your computer with others on your network. In order to protect your drives from unauthorized access, you should protect the drive with a username and password. When you need to change the username and password, you follow the same procedure as you would to initially map a drive. You must additionally select the option to "Connect using different credentials." Once you enter a username and password, other network users can connect to the drive.
Double-click "My Computer" on your desktop. Click "Map Network Drive" in the menu bar at the top center of the screen.
Click the drive that you would like to change. Click "Browse" and select the network location to map, if the space is empty. If it is not empty, do not change its contents. Click "OK" when you have the proper location selected.
Click "Reconnect at logon" and "Connect using different credentials" and select "Finish." You must select "Connect using different credentials" to change the password.
Enter a new username and password you will use to connect to the drive. Make sure the "Domain" section reflects the name of your computer. If not, enter the name before the username. Separate the two with a backslash. For example: Computer-Name\UserName.
Click "OK." The mapped drive will appear as a drive in your "My Computer" folder.
