15.17. Enabling and Disabling the Global Catalog


You want to enable or disable the global catalog on a particular domain controller.


Using a graphical user interface

  1. Open the Active Directory Sites and Services snap-in.

  2. Browse to the nTDSDSA object (NTDS Settings) underneath the server object for the domain controller whose global catalog you want to enable or disable.

  3. Right-click on NTDS Settings and select Properties.

  4. Under the General tab, check (to enable) or uncheck (to disable) the box beside Global Catalog.

  5. Click OK.

Using a command-line interface

In the following command, <ServerObjectDN> should be the server object DN, not the DN of the nTDSDSA object:

> dsmod server "<ServerObjectDN>" -isgc yes|no

For example, the following command enables the global catalog on dc1 in the Raleigh site:

> dsmod server "cn=DC1,cn=servers,cn=Raleigh,cn=sites,cn=configuration,dc=rallencorp,dc=com"
-isgc yes

Using VBScript

' This code enables or disables the GC for the specified DC
strDC = "<DomainControllerName>"   ' e.g., dc01.rallencorp.com
strGCEnable = 1                    ' 1 = enable, 0 = disable
' ------ END CONFIGURATION ---------
set objRootDSE = GetObject("LDAP://" & strDC & "/RootDSE")
objNTDS = GetObject("LDAP://" & strDC & "/" &  _
objNTDS.Put "options", strGCEnable


The first domain controller promoted into a forest is by default also made a global catalog server. If you want additional servers to contain ...
