I have had the same exact problem in the past.  I tried the lockout tool and that helped determine which server/workstation was locking out ~my~ account.  For a long time I was just logging in as someone else while I tried to stop it from locking my account out.  What I finally did was in Active Directory I set my account to only have the ability to log on to specific machines.  So even if another server for some reason was attempting to log on as me, it wouldn't lock out the account after three attempts.  This will also help for hacking attempts when they try and spoof a user account with admin access to the network.  Good luck...a
