Hiding a SQL Server vs Turning Off SQL Browser Can anyone explain the difference between turning off the SQL Browser service and Hiding an instance through the SQL Server Configuration Manager?

I've always assumed they do the same thing and have have hidden the server as a backup in case the SQL Browser service ever gets turned on but cannot find any documentation confirming this.

Thanks in advance!

To hide an instance of SQL Server, you need to set HideInstance flag to YES.



When you hide an instance, it will indicate that sql server browser should NOT respond with information about this server instance. Note that hidden instances support only shared memory connections. TCP/IP is allowed (as long as the port is 1433 or you specify) [Thanks to @AaronBertrand for highlighting this].

SQL Server uses the SQL Server Browser service to enumerate instances of the Database Engine installed on the computer. This enables client applications to browse for a server, and helps clients distinguish between multiple instances of the Database Engine on the same computer.
