If it's like in the KB a bug in the TLS's implentation, then you have to call the support to get a fix. Sorry.. (there; http://support.microsoft.com/contactus/). That way they will make a KB revision.
Did you check this blog?
If it doesn't help, i think you should contact support as Yagmoth555 mentioned.

I opened a supportcase in june for this and yesterday received some good news :
Finally the fix is available for Win2008R2 SP1.
Surprisingly, no new KB has been issued but the current one (KB2888853) was complemented by statements for W2008R2 SP1.
So when you go to download the fix, you can choose the Fix for Win2008R2 SP1.
