Hi, I'm having a Kerberos issue in IE8 on Windows 7. It's exactly the same issue as Paul Lynch mention here: http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/f649df36-a61b-4d23-a0c6-818dc2eff923 "I'm using IE8 on Windows 7. I'm testing a web site which requires Kerberos authentication for delegation. The web site URL is registered as a CNAME in DNS and the SPN for the site reflects this CNAME. " This is my case as well. Is there a solution for this behavor? I have made the registry change as descibed in http://support.microsoft.com/default.aspx?scid=kb;EN-US;938305 and http://support.microsoft.com/default.aspx?scid=kb;EN-US;911149 but that has no effect.
