Database connections not verified
Verifying a network connection confirms that a server is receiving requests on the computer name and port number specified. It does not verify anything about database connections.
Ensure that the database server is running.
Click the server entry in the Server box of the DSEdit session window.
Choose Ping Server from the Server Object menu.
The Ping window appears.
Select the address you want to ping. Click Ping.
A message box appears, notifying you whether or not the connection is successful. A message box for a successful connection states that both Open Connection and Close Connection succeeded.
