A few weeks ago I posted about an issue that we were having with our Windows Server 2008 machines Blue Screening, at the time I thought it was related to VMWare ESX Server, it turns out that it was a bug with Windows Server 2008. Thanks to Thomas Vochten for the pointer.
See: http://support.microsoft.com/kb/962943
“FIX: You receive a Stop 0x0000007e error message on a blue screen when the AppPoolCredentials attribute is set to true and you use a domain account as the application pool identity in IIS 7.0”
“Note This problem typically occurs on Web servers that host Office SharePoint Server 2007. This problem occurs because of the configuration requirements of Office SharePoint Server 2007 when Kerberos authentication is used. However, the problem may occur for any kind of Web site that is using Kernel Mode authentication, Kerberos authentication, and a domain account as the custom application pool identity.”
