Jobos Posted February 22, 2010 Posted February 22, 2010 I've got a problem with the Kerberos service on a server 2003 box that I don't know how to fix When the server is restarted it's taking a very long time before the logon box appears and I'm getting errors about the kerberos service hanging. Here is the time line from the event log: 8:34 event log started 8:38 kerberos key distribution centre hung on startup 8:53 Application popup warning about service not starting 8:56 kerberos key distribution centre starts There are two servers (server A and server B) and it's server A with the problem. I've run dcdiag on both servers and it reports no problem but netdiag on server A reports “kerberos does not have a ticket for host”.

I've run dcdiag on both servers and it reports no problem but netdiag on server A reports “kerberos does not have a ticket for host”. Netdiag often returns “kerberos does not have a ticket for host” because the Server 2003 version of netdiag doesn't work properly. Have you tried using Klist instead? It's in the Resource Kit. That may provide more useful information.
Jobos Posted February 22, 2010 Author Posted February 22, 2010 I have, but I don't know what I'm looking for! Server A has 7 cached tickets and server B has 6 cached tickets.
mrmontymick Posted February 22, 2010 Posted February 22, 2010 I have, but I don't know what I'm looking for! Server A has 7 cached tickets and server B has 6 cached tickets. Does the server A have a TGT for itself? If you stop and restart the KDC once the server has started does it do it quickly or is it as slow as initial start-up?

mrmontymick Posted February 22, 2010 Posted February 22, 2010 Sorry to sound thick but what does TGT mean? Sorry, way to geeky moment there, TGT = Ticket Granting Ticket. The master ticket if you like which allows you authenticate to all other Kerberos services. The restart question is probably the more important of the two to have an answer to....
Jobos Posted February 22, 2010 Author Posted February 22, 2010 (edited) KDC took 90 seconds to restart. I see from the event log that while KDC was restarting there were a number of crypt32 errors event ID 8 Failed auto update retrieval of third-party root list sequence number from: with error: This network connection does not exist All updates are done via WSUS on server B Edited February 23, 2010 by Jobos

The looks like it's trying to perform a security certificate update and is unable to do so.

I'll do the test again and this time test the internet when KDC is down.
Jobos Posted February 24, 2010 Author Posted February 24, 2010 I did a test before I went home tonight and the internet works fine when KDC service is stopped.
