While installing or when we want to use the SQL server if we receive an error message such as ‘sql server does not exist or access denied’, what must be done to solve this problem?
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.
