Installation Checklist

Before running the installation program, answer the following questions:

Does the target machine meet the system requirements?—See the "System Requirements" section.

Do you have the appropriate username and password for the target machine?—This is typically an administrative account. You must have administrative privileges to install Network Registrar.

What type of installation you want?

Both—Installs the servers and user interfaces—the recommended option

GUI—Installs only the user interfaces

Servers—Installs only the servers

In what directory do you want to install Network Registrar?—The default installation directory on Windows is C:\Program Files\Network Registrar.

Do you want to retain the ability to revert to a previous version of Network Registrar?—If so, you need to copy your database to another location. See the "Reverting to an Earlier Version" section.

Is this a new installation or an upgrade from Network Registrar 5.0 or 3.5?

If a new installation, see the "New Installation" section.

If an upgrade, see the "Upgrading From an Earlier Version" section.

If you need to upgrade from a version prior to 3.5, contact the Cisco Technical Assistance Center as listed in the Preface of this guide.

System Requirements

You can install the Network Registrar servers on one machine and the Network Registrar GUI on another. A GUI-only installation does not require as many system resources as a complete installation.

Server or Complete Installation

To run Network Registrar on Windows requires:

Equivalent of Intel" Pentium 200 MHz or better (Pentium Pro or greater recommended)

64 MB of RAM

Windows NT 4.0 workstation or server Service Pack SP4 or later (SP6a recommended), or Windows 2000 SP1 or later (SP2 or later recommended)

Network Registrar will crash if you run NT4.0 with no Service Pack installed. This crash occurs when you add recipients to the enabled SNMP traps. Network Registrar will also not operate optimally if you do not have at least SP6 installed.

50 MB plus 1 MB for each 100 clients managed by DNS or DHCP (a system managed by DHCP with dynamic DNS update counts as one client for this calculation)

Fastest available disk (for example, Ultra-SCSI) and mirrored or RAID disks with 100 MB free swap space

GUI-Only Installation

To run the Network Registrar GUI on a remote Windows machine, requires:

Equivalent of Intel" 80486, or Intel" Pentium or Pentium Pro

Windows 2000 or NT 4.0 workstation or server, with at least SP4 (SP6a recommended)

32 MB of RAM (48 MB for configurations of over 10,000 hosts)

50 MB of disk space

New Installation

To install the Network Registrar servers or the GUI on Windows, do the following:


Step 1 Close all open applications, including antivirus software.

Step 2 Log on to the target machine using an account that has administrative privileges.

Step 3 Load the installation CD-ROM or browse to the network resource where the Network Registrar software is located. If you downloaded a distribution file from the Cisco web site, run it in a directory from which you want to install Network Registrar. The distribution file is a self-extracting executable, and places the setup.exe and other files in the directory where you run it.

If your CD-ROM system is not configured for Autostart, run the Network Registrar setup.exe file located in the root directory of the installation CD-ROM or the installation directory.

Step 4 In the first and second Welcome windows, click Next.

Step 5 At the Question dialog box, click Yes to let the installation program test for Network Registrar components running on your machine and halt them if it finds them. If this is a new installation, none will be found. Click No to cancel the installation and halt these servers manually. When you click Yes, the User Information screen appears.

Step 6 At the User Information screen, enter your name and the company for which you work, then click Next. The Setup Type screen appears.

Step 7 At the Setup Type screen, choose the type of installation you want.

Both—Installs the Network Registrar servers and user interfaces—the recommended option

GUI—Installs the user interfaces only

Servers—Installs the Network Registrar servers only

At this point, you can also select a different location for the installation by clicking Browse. A standard Windows Choose Folder dialog box appears, where you can select a different folder. Click Next after selecting the folder, then click Next again to move on from the Setup Type screen.

Step 8 In the Start Copying Files window, click Next to begin installing the system files.

Step 9 After the installation is completed, restart Windows.

Step 10 After the system restarts, enter the license key so that you can administer the servers you have just installed. See the "License Key" section.


License Key

To administer the cluster of Network Registrar servers that you just installed, you must enter the license key, which enables the user interfaces. The license key is located on the back of the installation CD-ROM case.

You can run the user interfaces and the servers on different machines. You must tell the user interface which cluster you want to access and whether the cluster is on the local host or on a remote machine. (A cluster is a group of Network Registrar servers that share a database.)

If you have a permanent license, you must enter it once for each cluster that you want to access through the user interface. Once you enter the license key to access a Network Registrar server cluster, you are not prompted to enter a license key for that cluster again unless you move the cluster to another machine.

If you have an evaluation copy of Network Registrar, you have a license that expires.

If you have an invalid, missing, or expired license key, you cannot configure or manage the Network Registrar servers until you obtain a valid license key. However, the servers will continue to function normally.

On a new installation, enter the license key as follows:


Step 1 Start Network Registrar CLI or GUI from the Windows command line prompt.

To start the CLI, go to the C:\Program Files\Network Registrar/bin directory and enter:

# nrcmd -C clustername -U admin -P changeme 

Include the name of the Network Registrar server cluster, and username admin and password changeme. (You should change this password later on.)

To start the GUI, Select Start>Programs>Network Registrar 5.5 from the Windows Start menu.

Step 2 If you are using the CLI, enter the following command at the nrcmd> prompt:

nrcmd> license set key=keystring 

The keystring is the 16-digit license identifier found on the back of your installation CD-ROM case.

If you are using the GUI, when the Server Manager window appears, do the following:

a. From the Admin pull-down menu, select Clusters.

b. In the Cluster dialog box, click Add Cluster.

c. In the Add Cluster dialog box, enter the cluster name. This name is the host (DNS) name of the machine on which the Network Registrar servers are installed.

d. Select the "Connect to this cluster" check box, then click OK.

e. In the Login for Cluster dialog box, enter the username admin and password changeme, then click OK. (You should change this password later on.)

f. From the License dialog box, click New Key.

g. From the Cluster Properties dialog box, select Edit License Key.

h. Enter the 16-digit license identifier found on the back of your installation CD-ROM case, then click OK.

Step 3 Exit Network Registrar by entering the exit command from the CLI, or selecting Exit from the Admin menu in the GUI.


Upgrading From an Earlier Version

If Network Registrar 5.0 or 3.5 is already installed, you can upgrade to 5.5 while preserving your earlier databases, as follows:


Step 1 Back up the Network Registrar 5.0 or 3.5 databases. You cannot downgrade from 5.5, so you may need these.

Step 2 Close all open applications, including any antivirus software that is running.

Step 3 Log on to the target machine using an account that has administrative privileges.

Step 4 Load the installation CD-ROM or browse to the network resource where the Network Registrar software is located. If you downloaded a distribution file from the Cisco web site, run it in a directory from which you want to install Network Registrar. The distribution file is a self-extracting executable, and it places the setup.exe and other files in the directory where you run it.

If your system is not configured for Autostart, run the Network Registrar setup.exe file in the root directory of the installation CD-ROM.

Step 5 In the first and second Welcome windows, click Next.

Step 6 In the Question dialog box, click Yes to let the installation program test for Network Registrar components running on your machine, and halt them if it finds them. Click No to cancel the installation and halt these servers manually. When you click Yes, the Setup Type screen appears.

Step 7 At the Setup Type screen, choose the type of installation you want.

Both—Installs the Network Registrar servers and GUI (this is the recommended option)

GUI—Installs the GUI only

Servers—Installs the Network Registrar servers only

At this point, you can select a different location for the installation by clicking Browse. A standard Windows Choose Folder dialog box appears, where you can select a different folder. Click Next after selecting the folder, then click Next again to move on from the Setup Type screen.

Step 8 Click Yes at the question about upgrading your existing installation. This converts your existing databases into a 5.5 databases. Click No if you do not want to go ahead with the conversion.

Step 9 In the Select Program Folder window, click Next to confirm the installation folder.

Step 10 In the Start Copying Files window, click Next to begin installing the system files.

Step 11 During the course of copying the files and upgrading the databases, the installation program prompts you twice to enter your username and password. Enter your Network Registrar administrator username and password when prompted.

Step 12 When the installation has completed, restart Windows.



Note Upgrading to Network Registrar 5.5 from 5.0 or 3.5 automatically converts the DHCP failover and lease objects in the state database, but only those within a certain upgrade time frame (opportunity). The upgraded failover server gets from its partner all lease binding changes that occurred since the two servers last communicated. The upgrade time frame (without any server down time) depends on the number of leases issued or renewed each minute and the configured lease time. For example, if a configuration database upgrade takes 30 minutes and if there are 1000 leases with an expiration of six hours issued or renewed every hour, Network Registrar generates a maximum of 500 lease binding updates as part of the failover upgrade.


Uninstalling Network Registrar

To uninstall Network Registrar without preserving its database, use either the Add/Remove Program from the Windows Control Panel or the Network Registrar uninstall program from the Windows taskbar. Access the uninstall program using the following path from the Start menu:

Start > Programs > Network Registrar 5.5 > Uninstall Network Registrar

The Network Registrar uninstallation program removes the server and user interface components, but does not delete data that belongs to the user, such as the log and user data files. To delete the data associated with Network Registrar, first uninstall the application and then delete the Program Files\Network Registrar folder.

Re-installing Network Registrar

Infrequently, you may need to re-install the product because of a failure that could cause corrupted database files or if a file is accidentally deleted. On Windows, this is the same as a new installation. See the "New Installation" section for details.

Reverting to an Earlier Version

To revert to Network Registrar version 5.0 or 3.5, do the following:


Step 1 Back up the Network Registrar 5.5 database if you anticipate using it at a future date.

Step 2 Uninstall Network Registrar 5.5, as described in the "Uninstalling Network Registrar" section.

Step 3 Delete the Network Registrar 5.5 folder to remove the log and user data files that are not removed by the uninstall program.

Step 4 Re-install Network Registrar 5.0 or 3.5 as directed in the Network Registrar Installation Guide for that version.

Step 5 Stop the Network Registrar servers (as described in the "Starting and Stopping the Servers" section). Otherwise, you may get errors.

Step 6 If you are reverting to Network Registrar 3.5, copy the mcddb.d01, mcddb.d02, and mcddb.d03 files from their backup location, as in Step 1 of the "Upgrading From an Earlier Version" section, into the database folder of the Network Registrar installation directory. Copy and do not move the files.

If you are reverting to Network Registrar 5.0, you must also recover the data in CNRDB. You must run the cnrdb_recovery utility. For details on recovering the data, see the Network Registrar User's Guide.

Step 7 Change directories to the database directory.

Step 8 Run the keybuild tool to rebuild the key files. This can take several minutes.

installation-directory\bin\keybuild mcddb 

Step 9 Verify the integrity of the database by running the dbcheck tool.

installation-directory\bin\dbcheck mcddb 


Starting and Stopping the Servers

You can stop and start the Network Registrar servers (DNS, DHCP, and TFTP) from the Services feature of the Windows Control Panel. If the installation completed successfully and you did not stop the servers, they will run automatically and start each time the machine is rebooted.

All three servers in the cluster are controlled by a server agent. You can stop or start the servers by stopping or starting the server agent, as follows:


Step 1 From the Windows taskbar, select Start > Settings > Control Panel.

Step 2 In the Control Panel, click Services.

Step 3 From the Service list, select AIC Server Agent 2.0.

Step 4 Click Start or Stop, as required.

Step 5 Click Close.


What to Do Next

After you complete the installation, Network Registrar is ready for configuration. The details are specific to your network. However, the sequence of configuration tasks is generally as follows:

1. Add clusters

2. Add user accounts

3. Configure DNS server properties

4. Configure DNS zones

5. Configure DHCP server properties

6. Configure DHCP scopes (including policies, options, clients, and client-classes)

7. Customize server operations

Procedures for these tasks are included in the Network Registrar User's Guide.
