Before you install Essentials, ensure that your server and client environments meet the hardware and software requirements described in the following sections:
Installing Essentials is a multistep process that must be performed in a specific order. Depending on your system requirements, installing the software prerequisites might require three or more separate Microsoft software application installations, in addition to your specified options.
 | Caution The order in which you install the software is crucial to the successful installation of Essentials. You must install the software in the order specified, or you could disable your system. |
Ensure that your server meets the following hardware and software requirements, and software installation requirements.
For the server hardware and software system requirements for Essentials, refer to the "Before You Begin" chapter, "System Requirements" section.
This section describes the software that is required on the Windows NT system before you can install Essentials.
The following components of the Microsoft Windows NT 4.0 Option Pack must be installed on the system prior to Essentials installation:
There are several Microsoft software packages that must be installed on the system before you can install the Microsoft Windows NT 4.0 Option Pack.
The major steps required to install the required server software are as follows:
1. Verify that the system has Microsoft Windows NT Server 4.0 US English or Japanese version or Microsoft Windows NT Workstation 4.0 US English or Japanese version installed, and install one of them if none is installed.
2. Verify that Microsoft Windows NT 4.0 Service Pack 3 or Service Pack 4 is installed, and install it if it is not installed.
3. Verify that Internet Explorer 4.0 with Service Pack 1 is installed, and install it if it is not installed.
4. Verify that the required components of Microsoft Windows NT 4.0 Option Pack are installed, and install them if they are not installed.
The most important points of the installation process and an abbreviated sample procedure are provided in the "Installing Required Essentials Server Software" appendix for your reference.
| Caution If you are not familiar with installing the Microsoft Windows NT 4.0 Option Pack, refer to the "Installing Required Essentials Server Software" appendix and to the Microsoft Web site (www.microsoft.com) for additional information. If you install the required software incorrectly you will not be able to successfully install Essentials. |
Essentials installs a Web site on your system during installation. How this affects your ability to use other Web sites on the server system is dependent on whether you are using Windows NT 4.0 Server, or Windows NT 4.0 Workstation.
On Windows NT 4.0 Workstation systems, you can have only one Web site running at a time. When you install Essentials, any existing Web sites (including the default Microsoft site) are stopped so that the Essentials Web server can run.
On Windows NT 4.0 Server systems, you can have multiple Web sites running at the same time. You can run additional Web sites on the system, but this is not recommended for the following reasons:
During the Essentials installation, the installation tool determines whether Microsoft Internet Information Server 4.0 (for Windows NT Server), or Microsoft Personal Web Server 4.0 (for Windows NT Workstation) is installed on your computer, as appropriate for your version of Windows NT. If this software is not installed, the installation aborts.
Clients use a web browser running on a workstation or PC to access the Essentials server. The hardware and software requirements for client workstations or PCs are as follows:
Essentials supports clients running the browsers shown in Table 2-2.
| Browser | Version | Operating System |
|---|---|---|
Netscape Navigator1 | 4.05 and 4.5 | Solaris 2.5.1 or 2.6, Windows NT 4.0, Windows 95, AIX 4.2.1 or 4.3, and HP-UX 10.20 or 11.0 |
Microsoft Internet Explorer2 | 4.01 with Service Pack 13 | on Windows NT 4.0 and Windows 95 |
| 1With Java and JavaScript enabled; with accept all cookies enabled. 2with Enable Java Programs and Active-X Scripting enabled; with accept all cookies enabled. 3With Active Desktop disabled. |
To configure a client system to use with Essentials, follow these steps:
Step 1 On Microsoft Windows systems, set the display to use small fonts.
(a) Select Start > Settings > Control Panel. The Control Panel window appears.
(b) Double-click the Display icon. The Display Properties dialog box appears.
(c) Click the Settings tab. If Small Fonts is selected in the Font Size list, your display font is set correctly; go to Step 2.
(d) Select Small Fonts from the Font Size list, then click OK. The System Settings Change dialog box appears.
(e) Click Yes to restart your system. Windows restarts using the small display font.
Step 2 Configure the Web browser.
(a) Enable Java and JavaScript.
(b) Set your browser cache to at least 4 MB.
(c) Configure your browser to accept all cookies.
(d) Configure your browser to compare each page with its cached version every time it loads a page.
(e) (Internet Explorer only) Set the security level to Medium. Select View > Internet Options > Security, then select the Medium (more secure) radio button and click OK.
(f) (Internet Explorer only) Change the default timeout value to 20 minutes. Instructions are provided on the Microsoft Support Web site at the following URL:
http://support.microsoft.com/support/kb/articles/q181/0/50.asp
(g) Enable style sheets.
(h) Change the default font to a sans serif font for improved readability.
If you experience browser problems after configuring your browser as described above, increase your disk cache settings.
After the web browser is installed on the client machine, there are no additional disk space requirements. However, because the browser uses the local machine's disk to store cached information, make sure you have enough disk space for the amount of cached information you want to store. All Essentials information is stored on the Essentials server.
Essentials lets you import device information from both local and remote network management databases. You can import remote devices from a UNIX workstation running the supported versions of CiscoWorks, HP OpenView Network Node Manager, or CiscoWorks for Switched Internetworks (CWSI).
Essentials can be installed on the same machine as HP OpenView, CiscoWorks Windows 3.x, and CWSI Campus without any compatibility problems. If you plan to install all products on the same machine, check the compatibility notes of each product.
Table 2-3 lists the software that Essentials supports for importing device information from local and remote systems. You can import devices remotely from a UNIX system only. Essentials does not support remote device imports from Windows NT systems.
| Local Import | |
|---|---|
| Software | Version |
HP OpenView Network Node Manager | 5.01, 5.02 |
CiscoWorks for Switched Internetworks (CWSI) | 2.1 |

| 1You can import remote devices from the listed software running on a UNIX system only. |
In addition to the standard network ports (Telnet, TFTP, etc.) Essentials uses the following TCP and UDP ports:
Essentials uses port 1741 for the HTTP server. Make sure that you append :1741 to the end of your server name when accessing the Essentials server through your browser, for example:
http://server_name:1741
Refer to the "Setting Up Essentials" chapter for more information about accessing the server. Refer to the "Troubleshooting" appendix if you encounter problems.
