1. When data is exchanged between the client and the domain controller, each client occupies about 400-K of system resources, that is, about computers in SMT are added to the domain, therefore, when a policy is applied to the client, the system allocates the following resources to the client: 400*400 K or 200 * K, which may be between-M, although the probability of applications to each client at the same time is small, the domain controller should have the function and stability to process data
