In order to prevent possible attacks and whatever kind of malice trick from outside, the access to the Ms Sql server is limited to only the machines connected to our net. Therefore with a web space on and with a dedicated server the connection is guaranteed, while from the outside you will not be able to connect yourself as it purposely blocked: therefore tools such as Enterprise Manager and Query Analyzer will not be directly usable and direct connections to the host through dynamic functions of certain editors, where the connection, relating to localhost must be entered and modified during the upload on the server (e.g., Dreamweaver®).
