In Office Communications Server 2007 R2, multiple services can be associated with an individual server role. Changes to some settings require that you stop and restart one or more services. The following table lists the Office Communications Server 2007 R2 services and explains when you must stop and/or restart a service.

Note:
In addition to the service requirements that are described in the following table, we recommend that you stop the appropriate services for the server role before deactivating a server role to ensure that no users are connected to the server when you deactivate it.
