Last night in I lost power to my building and all my servers. This morning while recovering from the outage I have four Windows XP boxes that when a user attempted to log into the box using a domain account served from a Samba PDC, the windows box complained saying something like 'loss of trust with the domain controller'. My solution (which worked) is to remove the offending windows box from my samba pdc domain, then add the offending windows box back to the samba pdc domain. After these steps the user could log in without error. My question is why the loss of trust?
