If an external crossRef object is created and a domain controller uses it to generate a referral, the crossRef object provides two important data elements in the following properties. For more information about situations where this can occur, see the previous section.
|dnsRoot||Specifies the server or domain that can serve data from the naming context specified in nCName.|
|nCName||Specifies the distinguished name for the domain, schema, or configuration container rooted at the server or domain specified by dnsRoot.|
For example, if the server with DNS address of serv1.northwest.Fabrikam.com serves the naming context rooted at CN=MyContainer,OU=MyDOM,O=Fabrikam, set the dnsRoot to that server's DNS address and the nCName to the distinguished name of the domain, schema, or configuration container.
For more information and a code example that shows how to create an external referral, see Example Code for Creating an External crossRef Object.
