Question

account locked out because of too many failed login attempts

Asked by: level9tech

I think someone is trying to hack into our network. about every 20 mins I get an error in event viewer saying account has been locked out. Is there a way I can change the lockout period to be greater than like 20 mins. when an account has been locked out? and also is there any tool or anything I can get or use to find out more about who would be trying to hack into our network? like from where the login is tryin to happen? or what account theyre trying to login as? Thanks,

This could be someone attempting to break a password, or it could be a service trying to run with an account for which the passowrd has been changed. Check in event viewer to see if there is any indication of a serivice trying to start and failing. If you find such a service, locate it in Administrative Tools, Services and view its properties and the account it is trying to use to run.  If you are going to assign credentials to a service set up a special account for the purpose, give it a password and set it not to expire.

Check to see if the account user is using a secondary machine (possibly not on the domain), that use the same user account but with old credentials.
I have seen this with laptop users that use the same domain account name, then have mapped drives or printers using the domain account. They change their domain account password, but not the laptop or secondary machine local password to match.
