User Account Repeatedly locks-up

Posted on 2006-05-01
Last Modified: 2008-12-04
I have a user whos account continues to lock up intermitently. I have had him work out of a seperate workstation and his account has locked on that one as well. I dont believe it is his local profile because its happened on different pc's. I have done virus/adware/malware scans on his pc and found a couple of non-critical files that i deleted easily enough. Im really at a stopping point and not sure what else it could be. We are a MS shop, with AD running.

Any advice is welcome and appreciated.

    lock up or lock out?  Do you have to physically enable his account, is there a service somewhere that tries to login as the user to launch a scheduled app?  Almost sounds like a password lockout.  If this is the case, check security logs on machines that the user sits at and servers that the user accesses to see if there is a scheduled app that might have an old password.

    The first thing that comes to mind is did he change his password recently?  This can cause all sorts of problems but mainly if he uses multiple computers and is still logged into one of those computers with his old password, it will lock out the account.  If thats not it there are some account lockout tools you can download from Microsoft to help troubleshoot.  You can download the tools at
    and some general info about the tools and some things to check for at

    I have had this happen as well.  It is usually due to a change that the user is making to make things more "comfortable" for them.  In my case, it was as simple as a user moving a toolbar from the top of Microsoft Word to the left side (damm Softwise).  The only way I could find it was to start the user with a clean profile, then have them write down EVERYTHING they did.  Even then it took a week because the user did not think that moving a toolbar was that big of a deal.  The user MUST WRITE EVERYTHING they do.  

    Good Luck

    have u enforced any sort of password policy through gp . it is possible that ur client is trying to start any application or some thing else which requires domain acc & password and the credentials provided there r wrong and when he tries to acces that resource due to that policy his account locks out . chk event viewer for the error or warning

    I will try your opinions and post back. Thus far i have disjoined him from the domain, renamed his old local profile to .old, rejoined to domain, copied his data to newly creadted local profile. Lets see how that gopes.

    Thx for the tools kjmeldrum i have emailed them to my admin and he is researching that portion for me.

    Thx for the help all.

    If you use terminal server in your environment, make sure the user isn't just hanging on to a terminal session (possibly in a disconnected state).
    If the user changes their password but still has a Terminal session around, that can cause the lockout too.

    Also check any services or .exe that run at startup. Make sure nothing is automatically starting up with his username and old password.

    Thanks kjmeldrum!

    Your tools helped point out that there was a service running on another machine with his profile which continually locked our users account. We removed the machines from the network and the issue was stopped. once these two machines were placed back onto the domain his account locked out again.

    Thanks for the help to everyone!
