Major Reasons for SQL Server Does Not Exist or Access Denied

Let’s have a look at the major reason with a bit of explanation for users. This can help in finding the root cause of the problem. The major ones are:

  1. Major Firewall Errors – SQL Server Does not Exist or access denied is a common error that occurs if a firewall restricts access to SQL Server. It’s crucial to configure the firewall if it permits connections to the SQL Server. Moreover, incorrect login credentials like SA password or user ID will also result in this critical error. Cross-verification can help users to get the best solution.
  2. Wrong Server Name – Initiating to establish the connection with SQL without the correct Server name often causes this error as this is a very basic mistake by users.
  3. Required Permissions – Having insufficient permissions to access the SQL Server database is another major reason for getting this error.
  4. IP address of the SQL Server Instance is blocked the Firewall – To check SQL Server does not exist or access denied is occurring because of IP address, ping IP address on the command prompt like

    Ping –t

    If you are getting a response from the server then it means there is no issue with IP Address blockage but if not, then you need to an add exception (see point 4 above).
