Want to easily improve your SQL Server Skills? Before you dive in If you are NOT a DBA (Server Administrator) then read this. We had a number of online private chats using our website chat feature and we have identified there are a number of situations where you cannot do anything about it! We are aware some of you might be very new to this so I will provide you with simple list of questions or steps to check if you are in the 'cannot do anything about it' group. Before you start "fixing" it please go through the list below: Are you the person managing the server or the person who installed sql server (e.g. personal pc/laptop)? If no or you don't know, then there is a high chance you don't have permissions to fix it. What does it mean? It means you can only do what you are in control of (typing username, password) or trying steps that don't involve changing server configuration. If nothing works contact your server administrator (DBA). Are you connecting from an app (Visual Studio etc.) and not SSMS?
