http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/im_presence/ip_address_hostname/To change the IM & Presence service default domain setting from the default value of DOMAIN.NOT.SET, you must first stop certain services. The three services that must be stopped are:
A. Cisco XCP Router: The Cisco XCP Router service provides a messaging backbone for all XMPP-based Cisco collaboration applications. It is responsible for routing XMPP stanzas between different Cisco collaboration applications.
B. Cisco Intercluster Sync Agent: The Cisco Intercluster Sync Agent service synchronizes data between IM & Presence clusters in different domains. It is responsible for maintaining a consistent view of the user data across multiple IM & Presence clusters.
C. Cisco XCP Authentication Service: The Cisco XCP Authentication Service provides authentication services for XMPP-based Cisco collaboration applications. It is responsible for authenticating users who connect to the XMPP messaging backbone.
Stopping these three services is necessary because they are all dependent on the default domain setting of DOMAIN.NOT.SET. If you change the default domain setting without stopping these services first, you may encounter synchronization issues, authentication issues, or routing issues.
The other services listed in the answer choices, such as the Cisco SIP Proxy, Cisco Presence Engine, and Cisco AXL Web Service, are not directly related to the default domain setting of IM & Presence service and do not need to be stopped for this configuration change.
