Root Cause of the error → The error message "SQL Server does not exist or access denied" can appear when you're trying to connect to a SQL Server database. This problem can arise due to several reasons, including:
  1. Providing an incorrect server name
  2. Using incorrect login credentials
  3. Using credentials of a user who doesn't have permission to access the server
  4. The SQL Server Service not running
  5. The SQL Server Browser service being disabled
These issues prevent a successful connection to the SQL Server database.

Solution 
  1. Review the SQL Server configuration file to ensure the correct server name, login credentials, and password are configured accurately.
  2. Verify and adjust folder permissions for the Microsoft SQL Server installation directory.
  3. Check the status of essential services such as SQL Server and SQL Server Browser. If these services are not running, start them to enable database connectivity.
These steps aim to resolve issues related to server configuration, permissions, and service availability for successful SQL Server connection.
