You create a service and deploy it on a network in a building named Building1. You will deploy the service to Building2.

The service in Building1 is configured using the following discovery scopes.
<scopes>
<add scope=”http://contoso.com/Chicago/Building1″/>
<add scope=”ldap:///ou=Building1,ou=Chicago,o=contoso,c=us”/>
</scopes>

The service in Building2 will be configured using the following discovery scopes.
<scopes>
<add scope=”http://contoso.com/Chicago/Building2″/>
<add scope=”ldap:///ou=Building2,ou=Chicago,o=contoso,c=us”/>
</scopes>
