Comentários

When you install an instance of SQL Server, SQL Server Setup creates an entry in the Microsoft Windows registry that enables clients to see SQL Server in SQL Server Management Studio.

For security purposes, you can set TcpFlag to TRUE to hide a server on the network. Clients can still connect to it, but they cannot see the hidden server when viewing servers. You can reveal the server by setting TcpFlag to FALSE.

To set the TcpFlag property, you must be a member of the sysadmin fixed server role.

ObservaçãoObservação

If an application calls TcpFlag on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
Observação importanteImportante

Setting the TcpFlag property changes registry settings, and it should be used with caution.
