domain account keeps locking after changing

Hi All,

I have stupidly used my account somewhere down the line to run a scheduled task or specified in a service somwehere. Since changing my password i now continually locks out.


Is there anyway of tracing this other than rembering where i inserted this ?

You may want to check the "Security" logs in the Event Viewer on the Domain Controller to see if that will give you any hint as to where your invalid login attempt is coming from.  Other then that I do not know.

You can use some microsoft tools (account lockout and mgmt tools) to try and figure out where the offending machine/service is.  Good article on that here
