Maximum number of concurrent connections (0 = unlimited)

If set to a value other than zero, limits the number of connections that SQL Server will allow.

Caution:
Setting this to a small value, such as 1 or 2, can prevent administrators from connecting to administer the server; however, the Dedicated Admin Connection can always connect.

Default connection options

Specifies the default connection options, as described in the following table.

Configuration option	Description
disable deferred constraint checking	Controls interim or deferred constraint checking.
implicit transactions	Controls whether a transaction is started implicitly when a statement is run.
cursor close on commit	Controls behavior of cursors after a commit operation has been performed.
ansi warnings	Controls truncation and NULL in aggregate warnings.
ansi padding	Controls padding of fixed-length variables.
ansi nulls	Controls NULL handling when using equality operators.
arithmetic abort	Terminates a query when an overflow or divide-by-zero error occurs during query execution.
arithmetic ignore	Returns NULL when an overflow or divide-by-zero error occurs during a query.
quoted identifier	Differentiates between single and double quotation marks when evaluating an expression.
no count	Turns off the message returned at the end of each statement that states how many rows were affected.
ansi null default on	Alters the session's behavior to use ANSI compatibility for nullability. New columns defined without explicit nullability are defined to allow nulls.
ansi null default off	Alters the session's behavior not to use ANSI compatibility for nullability. New columns defined without explicit nullability are defined not to allow nulls.
concat null yields null	Returns NULL when concatenating a NULL value with a string.
numeric round abort	Generates an error when a loss of precision occurs in an expression.
xact abort	Rolls back a transaction if a Transact-SQL statement raises a run-time error.

Allow remote connections to this server

Controls the execution of stored procedures from remote servers running instances of SQL Server. Selecting this check box has the same effect as setting the sp_configure remote access option to 1. Clearing it prevents execution of stored procedures from a remote server.

Remote query timeout (in seconds, 0 = no timeout)

Specifies how long (in seconds) a remote operation may take before SQL Server times out. The default is 600 seconds, or a 10-minute wait.

Require distributed transactions for server-to-server communication

Protects the actions of a server-to-server procedure through a Microsoft Distributed Transaction Coordinator (MS DTC) transaction. For more information, see remote proc trans Option.
