Remove a Database Connection String (IIS 7)

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

Remove a database connection string when you no longer want to use a database to store data for your sites or applications. Remove an inherited database connection string when you want IIS to ignore a connection string defined at a parent level. Removing an inherited connection string enables your site or application to have a database connection that differs from the database connection of other sites or applications on the server.

noteNote
Removing a configuration setting removes the setting at the local level and from any child levels that inherit the setting.

For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform this procedure, see Database Connection Strings Feature Requirements (IIS 7).

You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.

appcmd set config /commit:MACHINE /section:connectionStrings /-"[name='Northwind']"
