Failed Logon/logoff: Event 537
Posted by rocketz21 on March 21st, 2007


Under the security event viewer, I've been receiving serveral failed
logon/logoff audits for event 537.

It says an error occured at logon. The logon process and authentication is
Kerberos and we don't use Kerberos.

Under the Kerberos policy in the domain security policy and dc security
policy, the kerberos policy isn't defined.

Anyone know why I'm receiving these failed audits or what's causing it?
