I had SQL Server 2008 running on a Windows Server 2003 machine in a Failover Cluster setup. Due to unplanned power outage, the cluster infrastructure failed and I had to recreate the cluster. I uninstalled SQL Server 2008 on the primary node and have been trying to reinstall it on the same machine (using the same installer) but the installation process triggers the error: "A severe error occured on the current command. The result, if any, should be discarded". I have also tried to install SQL Server 2008 in stand-alone on the secondary node and I still get the same error. As a result, the Management Studio cannot connect to the database engine. Please note that this is not the first time I've had to recreate the cluster after similar unplanned failure but this is the first time I can't successfully reinstall SQL SErver 2008. Has anyone encountered a similar situation? Please kindly advise on the way forward.
