Tech Tip: Query via the Indexing Service/Create superscopes

Windows 2000 Professional: Query via the Indexing Service

Last time, we explained how to add and remove directories from the System catalog managed by the Indexing Service. By indexing documents, the Indexing Service enables you to quickly locate documents using a variety of criteria, including filename, content, etc.

One way to search for documents is to go to Start | Search, choose For Files Or Folders, and specify the search conditions, such as document name. If you want to perform more complex searches, you can turn to the Indexing Service itself for help.

You'll find an Indexing Service branch in the Computer Management console. Navigate to Services and Applications\Indexing Service\System, expand the System branch, and click Query The Catalog.

The right pane displays an Indexing Service Query Form that you can use to enter search conditions and perform a query. When you click Search, the Indexing Service returns a list of documents that match the search conditions. To view a document, click its link.

The advantage to querying via the Indexing Service console is that you can specify more complex search conditions. To learn more about query structure, click the Tips For Searching link in the Indexing Service Query Form, and then click Query Syntax to open the Help file to view syntax and samples.

Windows 2000 Server: Create superscopes

The Dynamic Host Configuration Protocol (DHCP) service in Windows 2000 Server enables client computers to obtain an IP address and related IP network settings from a server. Dynamic allocation of IP addresses greatly simplifies network management.

A DHCP scope is a set of properties that defines a range of IP addresses and related settings such as default gateway and DNS servers. A scope can be active, meaning the DHCP server uses it to allocate addresses, or it can be inactive, meaning the server doesn't use the scope for address allocation. You can configure multiple scopes on a single DHCP server to service multiple subnets or IP ranges.

Windows 2000 Server also supports superscopes, a feature that simplifies DHCP administration. A superscope is a collection of scopes managed as a single entity.

You can use superscopes to support multinets, physical networks that contain multiple logical IP networks (a cohesive range of IP addresses). You can also use superscopes to support DHCP clients on the far side of a DHCP or BOOTP relay agent. The benefit of superscopes is the capability to activate and deactivate all the scopes in a given superscope with a single operation.

You can create a superscope on a Windows 2000 DHCP server only after you create at least one scope. Logically, you should create the scopes first and then create the superscope.

To create a superscope, follow these steps:

  1. Open the DHCP console on the server, and create the individual scopes if they don't already exist.
  2. Right-click the server where you want to create the superscope, and choose New Superscope.
  3. Windows 2000 starts a wizard in which you can specify a friendly name for the superscope and select the scopes to add to the superscope.

Windows 2000 automatically activates a superscope if one or more of the scopes contained in it are active. You can deactivate an individual scope in a superscope if needed, or you can deactivate all scopes by deactivating the superscope itself.
