Windows account locking itself

In particular my account.

After testing a fingerprint scanner my account is locking every time.
I've managed to track it down to my desktop that's causing it, but cannot see what it is.

I'm getting the following event log on the domain controller:

Kerberos pre-authentication failed.

Account Information:

   Security ID:  ACME\administrator
   Account Name:  Administrator

Service Information:

   Service Name:  krbtgt/acme

Network Information:

   Client Address:  ::ffff:10.42.42.224
   Client Port:  50950

Additional Information:

   Ticket Options:  0x40810010
   Failure Code:  0x18
   Pre-Authentication Type: 2

Certificate Information:

   Certificate Issuer Name:  
   Certificate Serial Number:  
   Certificate Thumbprint:

Certificate information is only provided if a certificate was used for pre-authentication.

Pre-authentication types, ticket options and failure codes are defined in RFC 4120.

If the ticket was malformed or damaged during transit and could not be decrypted, then many fields in this event might not be present.

Keep me up-to-date on the Windows Security Log.
