Ksetup:delkdc

Published: May 25, 2011

Updated: April 17, 2012

Applies To: Windows Server 2008 R2

Deletes instances of Key Distribution Center (KDC) names for the Kerberos realm. For examples of how this command can be used, see Examples.

ksetup /delkdc <RealmName> <KDCName>

 

Parameter Description

<RealmName>

The realm name is stated as an uppercase DNS name, such as CORP.CONTOSO.COM, and it is listed as the default realm when ksetup is run. It is to this realm from which you are attempting to delete the other KDC.

<KDCName>

The KDC name is stated as a case-insensitive, fully qualified domain name, such as mitkdc.contoso.com.

These mappings are stored in the registry in HKLM\System\CurrentControlSet\Control\LSA\Kerberos\Domains. To remove realm configuration data from multiple computers, use the Security Configuration Template snap-in and policy distribution instead of using ksetup explicitly on individual computers.

On computers running Windows 2000 Server with Service Pack 1 (SP1) and earlier, the computer must be restarted before the changed realm setting configuration will be used.

To verify the default realm name for the computer, or to verify that this command worked as intended, run ksetup at the command prompt and verify that the KDC that was removed does not exist in the list.

The security requirements for this computer have changed so the link between the Windows realm and the non-Windows realm must be removed. First, determine which association to remove and produce the output of existing associations:

ksetup

Remove the association by using the following command:

Ksetup /delkdc CORP.CONTOSO.COM mitkdc.contoso.com
