I get several of these events logged at my domain controller:
Source: Security
Category: Account Logon

Pre-authentication failed:
User Name: shamoo
User ID: mydomain\shamoo
Service Name: krbtgt/mydomain
Pre-Authentication Type: 0x2
Failure Code: 0x18
Client Address: 10.10.100.100

according to what I've found so far it means 'clients credentials have been
revoked'. That is straight from the Kerberos 5 RFC 1510 listing for error
code 18.

a couple ?'s:
1) why do they happen?
2) is there something wrong that I need to take action on?
3) I have noticed that some of the 'client address's' listed are 'the'
domain controller's address and some are actual client addresses? all other
things are the same?
