Perhaps I'm being dense here, but is there a service pack released for Server 2008 R2? I've just upgraded Server 2008 (which was due SP2) to R2 because of a memory leak issue we were experiencing. I thought the 2008 SP2 would apply but it says, probably correctly, that 2008 R2 is not a compatible product.
I can't seem to find anything about an SP for 2008 R2 - is this true. I have installed the basic updates via Windows Update.
