We were unable to determine the cause of the mysterious attempts to lockout the domain admin administrator account. There were no services or scheduled tasks that used that account and even using "rundll32 keymgr.dll,KRShowKeyMgr" showed no cached credentials on any of the computers. The DC's security event logs are being flooded with 0x12 and 0x18 errors for eventids 675 and 680. I am interested in also seeing what the lists suggests for tracking this down.
