Re: Event ID 3 Kerberos KDC_ERR_S_PRINCICAL_UNKNOWN



Can you post the actual message shown from the event log. There should be a
copy function, just paste it in to the news reader.

Hi Paul,
Thanks for the reply.
I have enabled logging and this is where the messages are coming from.
I am seeing these messages (0xd and 0x7) on the only 2 DCs. Not too sure
why
there is the cifs/127.0.0.1 setup as the Server Name and Target Name.
Where
would these be set?

Running Kerbtray, I see that when I am logged in I have connections to:
cifs/SAN1 (not 127.0.0.1)
host/DC1
krbtgt/domain.loc

When I look at the Encryption types, the Ticket Encryption Type and Key
Encryption Type are the same for cifs and host but the Key Encryption Type
is
different (etype 0) for the krbtgt.

Cheers
Giles

From what it appears, a client is making a request for a ticket for a
service that Kerberos doesn't know about.

You can enable tracing on Kerberos to see if you can determine what is
going
on:

You can also look at tickets currently used on your client with a Windows
Resource Kit executable named KerbTray.exe.

Hello,
I am getting a load of these errors along with KDC_ERR_BADOPTION

well.
We get users having very slow logons.
