error while verifying sql server database in coldfusion administrator

Connection verification failed for data source: HEMJOBS03 java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host开发者_开发知识库 and port: localhost:90. Reason: Connection refused: connect The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:90.

Looks like datasource configuration uses port 90 to connect, which is closed. See this chunk of your error Error establishing socket to host and port: localhost:90.

So, obvious question: have you changed the connection port manually? If yes, are you sure it is correct port?
