    Question

  • hi

    i install sql-server-2008 R2 on new computer Server-2008

    its work excellent, but when i try to connect from other computer i got this error:

    A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 1326)

    i disable the Firewall and i check ping from the computer to the server.

  • How about you put IP of that machine as Server name in Management studio? Can you ping that IP?


    Many Thanks & Best Regards, Hua Min

    Make sure that SQL service browser is in running state.
