Windows Server 2008: How to Verify Global Catalog Server Readiness

  • Article

Operating System

Windows Server 2008, Windows Server 2003.

Scenario

After enabling the global catalog role on a domains controller, we might want to ensure that it is properly functioning as a global catalog server before clients and services start querying the global catalog partition on this server.

How To

When a global catalog server has satisfied replication requirements, the isGlobalCatalogReady rootDSE attribute is set to TRUE and the global catalog is ready to serve clients.

To perform the following procedures, you must be a member of the Domain Users group.

To verify global catalog server readiness by using LDP, perform the following steps:

1. Log on to a domain controller.

2. Click Start, click Run, type LDP, and click OK.

3. On the Connection menu, select Connect.

4. In the Connect box, type the name of the server whose global catalog readiness want to verify, as shown in the following figure:

 

5. In the Port box, if 389 is not showing, type 389.

6. If the Connectionless box is selected, clear it and then click OK.

7. In the details pane, verify that the isGlobalCatalogReady attribute has a value of TRUE, as shown in the following figure:

 

Verify Global Catalog Server Readiness by using NLTest

To verify global catalog server readiness by using NLTest, perform the following steps:

1. Log on to a domain controller.

2. Click Start, and click Command Prompt.

3. In the Command Prompt window, type the following command:

nltest /server:servername /dsgetdc:domainname

(where servername is the domain controller you want to validate global catalog readiness and domainname is the name of the domain to which the domain controller belongs).

4. Verify that GC is listed under the Flags section of the results, as shown in below figure.
