Multiple Instances with Different IP Addresses and Same Port Number in SQL Server

  • Are they created automatically for 2008 cluster?

  • I am having the same issue. I've tried/set all the options as oulined, but still am not able to connect to the server directly (eg:dbservername), only by using servername\dbserversname, or by setting up a local alias (dbservername=servername\dbservername), or a third way (using dbartisan for example, servername:port number).

    Is there anything else that could be an issue?

  • I know this is an old discussion, but it came up when I was googling the interwebs for info on this.

    1. You need to understand DNS.

    2. You need to configure your server's network config correctly; i.e. do not register automatically with DNS Server

    3. Delete all A records from DNS and re-enter as static

    4. Disable listen all in your nework protocols

    5. Set ip's accordingly

    6. Set dynamic ports to nothing; i.e. delete anything there. Otherwise it will use it. 0 is not blank, it is "find something"

    Should all work.

  • We have a server with 3 instances of SQL Server running, each running on it's own IP and port 1433.

    I've created a blog post outlining how it was done.
