A Connection Could Not Be Established to LOCAL

  • Installed SQL Server developer edition on Win XP Pro laptop - using mixed mode authentication -

    When I try and connect in Enterprise Manager I get the following error:

    A Connection Could Not be Established to (LOCAL)

    Reason: Login failed for user SA...

    Please verify SQL server is running and check your SQL Server Registration Properties

    The SQL Service Manager is running under the name of my server -

    Appreciate any help anyone can give...

    THANKS

     

     

     

  • Login failed for user SA is sql authentication.

    Sure you haven't changed the password for SA?

    Can you login using windows authentication?

  • Hi - i decided to uninstall and try setting SQL up with Win Authentication instead of Mixed Mode - Now I am getting the error:

    A connection could not be establised to LOCAL

    Reason: login failed for user sa Reason: not associated wiht a trusted SQL server connection

    Thanks for the help

     

  • hmm

    normally a fresh install of sql server allows buildin administrators (local administrators of a pc) to login via windows authentication.

     

  • I know that is what is so confusing...the server manager is running under my server name also...

  • This problem appeared today out of the blue; does anyone have any idea what is going on here? I tried reinstalling MS SQL Server 2000 SP3 to no avail. Any help would be greatly appreciated.

  • Hi there,

    I have a similar problem.

    I can connect from a client to my sql server. But when I try to register it on the server with the enterprise manager. I receve an error message like

    "invalid option/identifier "
