## About AutoAdmin

(Communicator Professional Edition Only)

The Netscape AutoAdmin application provides remote configuration and management of Netscape Communicator components. Used in conjuction with the Netscape Mission Control product, the AutoConfig feature permits the centralized configuration of group or individual Netscape Communicator preference options, such as email, network, and security feature settings. Netscape AutoAdmin also provides centralized management of the download, installation, and upgrade of software components, including plug-ins. The AutoUpdate feature enables administrators to schedule clients to check automatically for new preference settings and software, at an interval that the administrator can set. AutoAdmin also enables adminstrators to "lock" desktops so that only preferences and Communicator customizations that are set by the administrator can be used, which greatly reduces support costs and effort.

Features of AutoAdmin include:

- Allows central configuration of Netscape Communicator client preferences
- Downloads, installs, and upgrades Netscape Communicator components and plug-ins automatically
- Restricts downloadable components to those authorized by the administrator

AutoAdmin is designed to be used by administrators, so there are no user-interface items that users need to set to enable AutoAdmin. For further details about Netscape Mission Control and how to use that product in conjuction with AutoAdmin, see your Netscape account representative or information at the Netscape site (http://home.netscape.com).

## About User Profiles

### An overview of user profiles and sharing Communicator with others

Note that user profiles apply to Macintosh and Windows only. For Unix, create another user account instead of creating Communicator profiles.

When you start Communicator for the first time, it prompts you to create a user profile. User profiles let more than one person use Communicator to access the Internet in different ways. For example, if you share your copy with other users, each of you can create your own user profiles to keep your settings, preferences, bookmarks, and mail messages separate. Even if you are the only person using Communicator, you must create at least one profile for yourself.

If you want to, you can create several profiles just for yourself, for example, if you want to connect to a different service provider to try out their service without cancelling the account you have with your current service provider.

## Creating User Profiles

Note that user profiles apply to Macintosh and Windows only. For Unix, create another user account instead of creating Communicator profiles.

### To create additional user profiles

1. (Windows) If Communicator is running, from the File menu choose Exit.

   (Macintosh) If Communicator is running, from the File menu choose Quit.

2. (Windows 95 and Windows NT) From the Start menu, choose Programs, then Netscape Communicator, then choose Utilities, then User Profile Manager.

   (Windows 3.1) Open the Netscape Communicator program group, and double-click User Profile Manager.

   (Macintosh) Open the Netscape Communicator folder, and double-click User Profile Manager.

3. Click New.
4. Follow the Profile Setup instructions that appear.
