Can not connect to SQL Server Instance

  • I have SQL Server 2012 installed and when I run this command:

    sc query mssql$MSSQLSERVER

    I get this error:

    [SC] EnumQueryServicesStatus:OpenService FAILED 1060:

    The specified service does not exist as an installed service.

    I run this command on the same server where SQL Server is installed. Databases are on the same server too. TCP/IP is enabled for the instance and port 1433 is open on the server's firewall. SQL Server Browser is running.

    Many errors in the SQL Server error logs like:

    SQLServer Error: 11001, A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct.

    SQLServer Error: 11001, TCP Provider: No such host is known. [SQLSTATE 08001]

    Any ideas what could have gone wrong?

    Thanks,

    From a CMD prompt, can you successfully ping the server like so:

    PING mssql$MSSQLSERVER

    Otherwise, try connecting using IP address instead of server name.

    You can successfully ping remote server name from client?
