Cluster up and down

  • i'm new to clustering and wondering what's going on.

    one of my clusters is going back and forth between nodes, and not staying on either.

    i'm thinking it's the startup account.

    how do i change the startup account for my SQL cluster?

    Thanks

  • Ensure the SQL Server Service account is  a domain account and has access on the both the nodes.

    SQL Server Service account can be changed on Enterprise Manager.

  • What does the error log for SQL Server indicate? Anything in the system or application event logs? Usually if they're boucing there'd be something in the Windows logs as to an error occuring.

  • our mssqlserver service will not come up, even though we have verified that the password is correct.

    it will 'bring online' and we are temporarily able to connect, but then fails.

  • Do you have any group policies that make changes to settings like "Log on as a service" or "Act as part of the operating system" or "Log on as a batch job" that would effect the cluster? Also, are you seeing any errors in any of the event logs or in the SQL Server error log itself?

  • ok think i've found the problem.

    builtin administrators was disabled.

    wasn't aware this was needed to run the cluster.

    my fault.

  • i disabled builtin administrators last week, but this problem didn't happen until now, why is that?

    i understand that the domain account wasn't able to login, when i disabled the builtin admin.

    thanks for the help

  • BUILTIN\Administrators isn't needed, but before it is removed the SQL Server service account and the Cluster service account both need to be added and given sysadmin rights. More here:

  • I can't believe i did that without checking.

    Thanks
