Kerberos Logon Failure / Error

[mjstanton]

Hi, I need help with errors in the Security section of the event viewer on our W2k DC.

On a daily basis there are at least 50 of these entries:

Event ID: 537
Source: Security
Category: Logon/Logoff
Type: Failure Audit
User: NT AUTHORITY\SYSTEM
Computer: Servername (this is a windows 2000 domain controller)

Description:
Logon Failure:
Reason: An unexpected error occurred during logon
User Name:
Domain:
Logon Type: 3
Logon Process: Kerberos
Authentication Package: Kerberos
Workstation Name: -

What do these mean and how can I get rid of them?

Thanks in advance for any/all replies!

MJ

Check your ipsec settings on all the machines. They should be the same. It sounds like some machines do not have the same security negotiation settings.

Aren't ipsec settings for VPN tunnels?

They pertain to anything ip.... tcp/ip etc
