Server Name

The name of the SQL Server instance. You can choose the up arrow to select the server from the Available Microsoft SQL Servers window, or you can enter the server name manually.

Database Name

The name of the database that you want to open. You can choose the up arrow to select the server from the Available Databases window, or you can enter the database name manually.

Authentication

The authentication type that you want to use to connect to the server. You can select Database Server Authentication or Windows Authentication.

User ID

If you have selected Database Server Authentication in the Authentication field, then you must enter a user ID.

Password

If you have selected Database Server Authentication in the Authentication field, then you must enter a password.

Net type

The network type to use to connect to SQL Server.

You generally do not have to change the network type from the default setting. The Default network type setting enables Microsoft Dynamics NAV to connect to a server by using the default client network type that is assigned by SQL Server. If you have installed SQL Server Client Utilities, then you can change the network type with the Client Network Utility, which is part of the SQL Server Client Utilities.

Attach file

If you want to attach and open a detached database that consists of a single data file, excluding the transaction log file, then you must enter the complete path and file name of the database in the Attach File field. This file typically has the .mdf file name extension. You can give this single file database any name by entering it in the Database Name field on the General tab. If no transaction log file exists with the data file, it is automatically created when you attach the data file. The database file is attached when you open it.
