If you’re installing a Windows Server 2008 R2 cluster on Windows Server 2012 R2, you may be hit with the installer asking you to install a Server 2003 hotfix referenced in KB 937444. The problem being, there is no chance that 2003 hotfix is going to install on a 2012 OS.
The issue is resolved in SQL Server 2008 R2 SP1 but if you’re installing from the RTM media you will be in a chicken and egg situation. You can’t install SQL Server 2008 without SP1, and you can’t install SP1 without getting the main SQL Server 2008 install done.
The solution is fairly tedious – you can create your own 2008 SP1 slipstream with a bit of extracting ISO’s and copying files and folders around. Don’t worry – it can all be done on disk – you don’t need to burn a DVD or anything like that.
The full details of the process are here –
It took about 20 minutes of dicking about, but the cluster install sequence sailed through once using the slipstreamed installer.
