Quoted from http://www.eventid.net/display.asp?eventid=675&source=Security

Michael Papalabrou: If you experience 675 errors or if you find your account locked out suddently on Win2000 networks after changing your domain password, ensure that you are not logged on another Win2000 machine (apart from the one from which you changed your password). The system tries to renew the Kerberos ticket using the old password and fails.

Erik Swenson: When a user attempts to log on at a Windows 2000 Pro workstation and uses a valid domain account name but enters a bad password, the DC records event ID 675 (pre-authentication failed) with Failure Code 24 (or 0x18).By reviewing each of your DC Security logs for this event and failure code, you can track every domain logon attempt that failed as a result of a bad password. In addition to providing the username and domain name, the event provides the IP address of the system from which the logon attempt originated. Windows 2000 also logs event ID 675 when a user attempts to use a different username (i.e. a username other than the one he or she used for the current workstation logon) to connect to a server.

I have not changed my password latelly, but my AD is messed up, so it was probably a rights issue that had not been replicadet, let's add that to the list of posibilities, no?
