Instance Name same as Server Name

  • We are trying to put SP3a on our SQL Server. Here is the problem :

    The default server name is :

    CATEST

    And the named instance server name is :

    CATEST\CATEST

    When we try to put SP3a on it for some reason it does not recognise the default instance name. Any idea why ? But Thur EM I can connect to both the instances.

    Any help is appreciated.

    Thanks.

  • Try renaming the named instance, apply sp3a and rename again if wanted.

    I think it is not wise to name an instance the same as the machine name. Specially if you already have a default instance...

    When you need more than one instance, it is recommended to install all instances as named instances.

  • I wonder if there's a way to change the instance name (part after \) other than reinstall server with different name. Service names, directories etc. have named instance name included, so I don't think it's possible.

  • What operating system are you running on and what network libraries are currently configured (Named Pipes, TCP/IP, etc.)? When you're connecting from EM, is this just locally or can you connect from a remote system?

  • Its on a windows 2000 Server with SP4. Yes I am able to connect to both the instances from other machines thru TCP/IP as they are running on different ports.

    Thanks.

     

  • Is the default instance listening on port 1433? Is there an alias in place that shoots it to the named instance (check by running cliconfg locally)?
