I have a user running a Mac and his account is getting locked out constantly. He claims that nothing is using old credentials and that he deleted his keypass. however, every couple days we get this in the domain controllers:

Logon attempt by:      MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
 Logon account:      <user name>
 Source Workstation:      \\workstation
 Error Code:      0xC000006A


Normally i would look at the source workstation area as it would tell me an IP address or valid computername. however, \\workstation never shows on our DNS or DHCP logs. and the microsoft authentication package v1.0 seems to be very generic from the searching i've done.

ive been using eventcoombt.exe and lockottstatus.exe to try and troubleshoot but i dont know where else to look. can install anything on this users mac or the DC's to get more detail or anything?

Is the user using a wireless device (smartphone, ipad, laptop) to connect to a service (exchange, internet) using his AD credentials?

If that is so, then this would most probably be the culprit, because if the user changes his password on his workstation, he has to do the same on every  wireless device connected. Otherwise the wireless devices would persist on attempting to login with the old credentials, hence locking his account constantly.

Phone the source workstation would indicate the IP of our exchange server. Which in this case it isn't.

Lots of good links. Thank you. The user told me today that he found manual entries in his fstab file. Even though this is something i mentioned to him earlier.
