Adds a service principal name (SPN) mapping between the stated host and the realm. For examples of how this command can be used, see Examples.

ksetup /addhosttorealmmap <HostName> <RealmName>

 

Parameter Description

<HostName>

The host name is the computer name, and it can be stated as the computer's fully qualified domain name.

<RealmName>

The realm name is stated as an uppercase DNS name, such as CORP.CONTOSO.COM.

This command allows you to map a host or multiple hosts that are sharing the same DNS suffix to the realm.

The mapping is recorded in the registry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentContolSet\Lsa\Kerberos\HostToRealm.

As part of configuring the realm CONTOSO, map the host computer IPops897 to the realm:

ksetup /addhosttorealmmap IPops897 CONTOSO

Verify in the registry that the mapping is as intended.
