# Shutting down the Network Server

To shut down a Network Server, you can invoke a script, a jar file, or a class.

The scripts to shut down a Network Server are located in the `$DERBY_HOME/bin` directory.

Important: If user authentication is enabled, you must specify a valid Derby user name and password; if the user authentication check fails, you'll see an authentication error and the running server remains intact. Note that Derby does not yet restrict the shutdown privilege to specific users: the server can be shut down by any user on the server machine who presents valid credentials.

- To shut down the Network Server by using the scripts provided for Windows systems, use:

      stopNetworkServer.bat [-h hostname] [-p portnumber] [-user username] [-password password]

- To shut down the Network Server by using the scripts provided for UNIX systems, use:

      stopNetworkServer [-h hostname] [-p portnumber] [-user username] [-password password]

- Shutting down by using the command line
- Shutting down by using the API
