>First, thank you for the explanation. Here is what I need to clarify for myself. For example, the customer (big organization) has a SQL Server installed on some server. They have many databases on this server. Now then need to allow me to attach my database to this server and maintain it. But they don't want me to see other databases or make any changes to them. So they have to install SSMS on my application server (where my VFP app resides). And when I use this SSMS I can attach my database and maintain it; without seeing other databases. So how do they (the customer IT) do that; create SSMS that only allows me to view/maintain one database?
