Each session has a dedicated process for its services for only a few client-connected servers or OLTP (online transaction processing systems)
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

For dedicated MSSQL database servers, open only 1433 and 5631 ports, as described above, to set up TCP/IP filtering and policy. For MSSQL, first you need to set a strong password for the SA, use mixed authentication, strengthen the logging of the database log, and audit the "success and failure" of the database login events. r
