Windows Server 2008 R2 CA server with OCSP responder returns incorrect thisUpdate value

Hi All,

I have identified an issue with a CA in my internal setup. The CA server is running on Windows Server 2008 R2. 

The thisUpdate field often gets populated with an older date, though the OCSP response being sent is fresh i.e even for a new certificate, where no OCSP response has been issued, the thisUpdate field gets set incorrectly. 

I found a hotfix that is supposed to resolve this : http://support.microsoft.com/kb/2635621/en-us?wa=wsignin1.0

However, this is applicable only for Windows Server 2008 and not for 2008 R2. 

Can anyone let me know if there is such a fix for Windows server 2008 R2 as well? 

Thanks,

Draghav
