For better performance results with the DNS/DHCP Management Utility, particularly in a distributed DNS/DHCP set-up, you should configure the DNS/DHCP Scope Settings for the session before you proceed with other administrative tasks.
If you do not configure the DNS/DHCP Scope Settings for the session, you will receive a warning before every task you attempt to perform that the Scope Settings are not set. However, you can still proceed with the task.
Setting the scope of the DNS/DHCP services involves two specifications for the session: the eDirectory context of the Locator object and the administrative scope of the session. Specifying the eDirectory context of the Locator object at the start of the session significantly improves performance because it eliminates the need to search for the Locator object. Specifying the administrative scope of the session also improves performance significantly because it restricts the retrieval of DNS/DHCP objects for viewing to the scope you specify.
The DNS/DHCP Scope Settings you configure for a session last as long as the session lasts. If you start a new session, you have to configure the DNS/DHCP Scope Settings again.
IMPORTANT: If you configure DNS/DHCP Scope Settings for a session for either DNS Management or DHCP Management, the settings apply across the session to both roles.
To configure DNS/DHCP Scope Settings, complete the following steps:
Click DNS Management or DHCP Management > DNS/DHCP Scope Settings to open the DNS/DHCP Scope Settings window.
Enter the eDirectory context of the DNS/DHCP Locator object.
Enter the eDirectory context of the container object that will provide the administrative scope of the current session.
NOTE: If you enter only the eDirectory context of the DNS/DHCP Locator object and not the administrative scope of the current session, you can proceed with administrative tasks without inviting a warning message. However, performance is further optimized if you also define the administrative scope.
Click OK.
