Hi I've found several documents describing that IE6 SP1 doesn't support kerberos-authentication and other documents like http://support.microsoft.com/kb/299838 which describes a solution, how I can enable the kerberos-authentication in IE6. I've enabled it and rebootet the client, but I'm not able to authenticate with kerberos with IE6 & Windows2000. Any hints or is it definitely not possible to authenticate the W2K-IE6 with kerberos? Thanks. Regards, Tom
