Is SQL Server 2008 R2 SP1 supported on Windows Server 2008 R2 SP1? I've found this website
https://support.microsoft.com/en-us/kb/2022909
where it says:
“SQL Server 2008 R2 is not supported onany version of Windows Server 2008 less than Windows Server 2008 Service Pack 2”
but I think this article is pretty old so it might not be up to date.
thanks,
