How can I get SQL Server Management Studio 2012 to connect to multiple servers automatically on open?
In Management Studio, go to the View menu and then Registered Servers. Register each of the servers that you want to keep connections for. Then when you open up Management Studio in the future, you just have to go to your register servers and click the ones you need. You can also use the Central Management Servers feature if there are multiple people on your team that would like to share the registered servers. You can group them in various ways, such as by version, by environment, by location, etc.
