HOW TO: Create or Move a Global Catalog in Windows 2000
IN THIS TASK
Summary
o How to Create a New Global Catalog on the Destination Global Catalog
Server
o How to Remove the Global Catalog from the Original Global Catalog Server
SUMMARY
=======
This article explains how to create a new global catalog server. This may
be necessary if you need additional global catalog servers (e.g. to support
an Exchange 2000 roll out) or if you want to move the global catalog server
role to a different domain controller.
There may be occasions when it is necessary to create a new global catalog
to replace an existing one, or to add a new global catalog. Microsoft
recommends the following method:
1. Create a new global catalog on a second domain controller.
2. Wait for the account and the schema information to replicate to the new
global catalog. For single domains, this is relatively straightforward. For
multiple domain networks, full replication will take additional time,
depending on the complexity of the network. The new global catalog will be
created by normal Active Directory (AD) replication and depending on the
structure of your AD forest, this replication could take considerable time.
3. Remove the global catalog from the original domain controller
(optional).
By default, Windows 2000 will only place a Global catalog on the first
Domain Controller in each AD forest.
To create additional global catalog servers, or to move a global catalog
from one domain controller to another, you need to perform these actions
manually.
How to Create a New Global Catalog on the Destination Global Catalog Server
To create a new global catalog:
1. On the domain controller where you want the new global catalog, start
the Active Directory Sites and Services snap-in. To start the snap-in,
click Start, point to Programs, point to Administrative Tools, and then
click Active Directory Sites and Services.
2. In the console tree, double-click Sites, and then double-click
sitename.
3. Double-click Servers, click your domain controller, right-click NTDS
Settings, and then click Properties.
4. On the General tab, click to select the Global catalog check box to
assign the role of global catalog to this server.
5. Restart the domain controller.
NOTE: Allow sufficient time for the account and the schema information to
replicate to the new global catalog server before you remove the global
catalog from the original domain controller.
Event 1119 may be logged in the Directory Services log in Event Viewer with
a description that states that the computer is now advertising itself as a
global catalog server.
In a Windows 2000 domain with only one domain controller, you typically
assign the roles of the global catalog and of the operations master (also
known as flexible single-master operations or FSMO) to the same domain
controller; however, in domains with multiple domain controllers,
particularly in forests with multiple domains, it is important to consider
the placement of these roles before you assign them. For additional

How to Remove the Global Catalog from the Original Global Catalog Server
To remove the global catalog from the original domain controller:
1. On the domain controller from which you want to remove the global
catalog, start the Active Directory Sites and Services snap-in. To start
the snap-in, click Start, point to Programs, point to Administrative Tools,
and then click Active Directory Sites and Services.
2. In the console tree, double-click Sites, and then double-click
sitename.
3. Double-click Servers, click your domain controller, right-click NTDS
Settings, and then click Properties.
4. On the General tab, click to clear the Global catalog check box to
remove the role of global catalog from this server.
5. Restart the domain controller.
NOTE: Allow sufficient time for the account and the schema information to
replicate to the new global catalog server before you remove the global
catalog from the original domain controller.
If you create additional global catalog servers, this may provide quicker
responses to user inquiries; however, if you enable additional domain
controllers as global catalog servers, this may increase replication
traffic on the network. For additional information about directory
