I have a Windows Server 2008 that have some problems.
When I try to add a member to a group (Remote Desktop Users) I get this dialog when clicking "Advanced" telling me "The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you
I tried to remove the machine from DNS to see if it reregistered, but it didn't (after reboot).
On the server where I am trying to add a user to a group, I get this event:
The Security System detected an authentication error for the server
ldap/DC2.MyDOMAIN.dk. The failure code from authentication protocol
Kerberos was " (0x80080341)".
