Fixed: SharePoint, IIS7 & Kerberos causing Blue Screens

Recently I enabled Kerberos authentication for my SharePoint web applications. Since then, we began to receive random blue screens. After analysis of the crash dump, we received the following error message:

BugCheck 7E, {ffffffffc000001d, fffffa6000000000, fffffa60005a5848, fffffa60005a5220}Probably caused by : HTTP.sys ( HTTP!UlAuthenticate+73 )

That immediately ringed a bell, as we implemented Kernel Mode Authentication by manually changing the applicationHost.config file on our webserver. The details on the why and how are detailed in these articles.

Microsoft recently published, that should solve this issue! At the time of writing, I could only find this KB via the Microsoft Support website โ€“ so it must be so recent that Google did not pick it up yet ๐Ÿ˜‰
