Error message ‘SQL server does not exist or access denied’

Error message ‘SQL server does not exist or access denied’

Hi

"SQL Server does not exist or access denied" is a generic Microsoft Data Access Components (MDAC) message that indicates that the computer that is running Microsoft SQL Server cannot be contacted. Additionally, the following error messages also have similar causes like SQL server is unavailable or does not exist or the specified SQL server is not found.

Some of the causes for this error are – it may not be installed in the computer which you intend to use, or the server may not be started, the server may not be connected to the port, it cannot listen to the TCP/IP protocol or the server name is different from the computer name. These may be some of the causes for this type of error. This can be corrected by properly and fully installing the latest server version with all the new fixes and establishing proper communication between the server and the system.

Error message ‘SQL server does not exist or access denied’

The error “SQL Server does not exist or access denied” is a generic or general message from MDAC or Microsoft Data Access Components which signifies that the machine running on Microsoft SQL Server cannot be reached or can’t be contacted. This message has many possible grounds. It is similar to the following messages which also have the same causes:

• * SQL Server is unavailable or does not exist.
• * The specified SQL Server is not found.

Here are several of the possible causes why the “SQL Server does not exist or access denied” error message is thrown. If there is not a single computer that can connect to the SQL Server computer, there is a possible server-side problem:

• * It is possible that Microsoft SQL Server is not installed on the computer. To fix, verify that Microsoft SQL Server is actually installed on the computer that you indicate in the connection string.
• * It is also possible that the SQL Server is not started or is not running. To fix it, the SQL Server should be running to be able to accept connections.

If there are several client computers or applications that are able to connect but there are others that cannot, you are probably having a client-side problem:

• * One of the possible causes is that the computer name doesn’t exist.
• * It is also possible that you are trying to access a named instance of SQL Server but the name you specified is incorrect.
• * There is also the possibility that the Windows-level security you are using to connect is different from what you expect.
