2.3.2.1 Network Connectivity
WSUS requires a networked environment in which clients and servers are connected. However, constant connectivity is not required; client and server implementations can take advantage of intermittent periods of connectivity to communicate. This requirement is necessary because a primary function of WSUS is to transfer update-related information between clients and servers and servers and servers. If the requirement is not satisfied, WSUS will not function. A temporary loss of connectivity can be mitigated by retrying the protocol operation at a later time.
