Windows Server 2008 Kerberos Bug Patch – resolves SSAS connection issues

Posted by denglishbi on July 21, 2009

Yesterday I was notified by a colleague that Microsoft had released the patch to fix the AES Kerberos issues that had been discovered earlier this year – Windows Server 2008 Kerberos Bug – Transport Connection Issues with SSAS data.  I had not been notified of this yet, but I checked out the blog posting by Dr. John Tunnicliffe SSAS: Microsoft release fix for “Kerberos killing MDX” issue and he provided a link to the downloads Smile

UPDATED (8/23/2009) *** This has been updated and is the official release for this fix now *** :

A Kerberos authentication fails together with the error code 0X80090302 or 0x8009030f on a computer that is running Windows Server 2008 or Windows Vista when the AES algorithm is used

*** This has been updated and is the official release for this fix now ***

So for those of you who have had to put the upgrade to Windows Server 2008 on hold because of this you can now download the patch and continue on with your infrastructure upgrades.  Just make sure that you properly test the patch before deploying this into your production environments.

    I deployed the 64 bit patch on my server, and it fixed the problem except for the very first time users load the page, one of the filters errors out with the same issue all the filters had before the patch was applied. You can hit refresh and everything will work fine. Does anyone else have this problem?
