SSAS: Microsoft release fix for “Kerberos killing MDX” issue

In a previous post I reported how small MDX queries worked fine when client and server were Windows Vista/Windows Server 2008 but large MDX queries died due to the connection been forcibly closed by the transport layer. It turned out that this issue was due to a bug in the Kerberos.dll on these AES aware operating systems. AES = Advanced Encryption Standard.

Microsoft have how released a hot fix for this issue.  Read John Desch's blog post for details.

Note that this bug is not present in the Windows Server 2008 R2 or Windows 7 release.
