"Provider: Shared Memory provider, error: 0-No process on the other end of the MPs queue" is prompted during SQL Server Authentication, that is, when the SA user name is logged on ".

A connection has been established with the server, but an error occurs during logon. When you log on to sql2005 Enterprise Manager, you can use Windows for authentication. However, when you use SQL Server for authentication, that is, the SA user name is logged on, the following error message is displayed: "provider: Shared Memory provision Program, Error: 0-No process exists on the other end of the MPs queue ". Later, I realized that the general problem occurred here. during recursion, I called the method for creating a subnode and once opened the database connection n times, but finally closed it only once, therefore, when you access this page multiple times, "you have successfully established a connection with the server, but an error occurs during logon. An error occurred while logging on.
