[jay]

Hello,im gettign these errors in event viewer,i went to
eventid.com and it didnt really give me what i need to fix
it,is there anything anyone knows about it,here is what it
says.

"The Security System could not establish a secured
connection with the server DNS/kid1.portrocker. No
authentication protocol was available."

Now kid1 is my server and portrocker is my domain.
here is the other error.

"The Security System detected an authentication error for
the server DNS/kid1.portrocker. The failure code from
authentication protocol Kerberos was "The attempted logon
is invalid. This is either due to a bad username or
authentication information.
(0xc000006d)"

now this errors were occurring over night when know one
was logging on,im thinking it referring to computer
account,any ideas here...

ok..under ADUC it says portrocker.com,which doesnt make since to
me,when clients join my domain i have to put just portrocker ,is it
supposed to be like that?

No it not supposed to be that way, it is a disjointed namespace *email* me
direct I have a script I can't post here for fixing just this.

You normally have to call Microsoft support to get it because it has to be
diagnosed. If your DNS domain name is portrocker.com and the DNS Suffix is
portrocker this works as long as your changing only the Primary DNS suffix.
