Account Keeps Locking out

Hi Guys,

We are using active roles in our environment and there is an account that keeps locking out.

How do I find out what's causing this to happen?

Regards,
Kay

You could check loggings on DC's to see what the originating name of the machine is that locks that account.
Normally though it is a device (i say device on purpose) that connects to your wireless network if account name is needed or it could be that someone is using cached credentials on a machine to the password keeps on being passed to AD.

Is the account one that is used by a user or an admin or a system?

I would disable to account in AD and then wait for either the user or admin to complain. Similarly if you notice a system has stopped working then you will be able to pinpoint where that account is in use. Although if it were a system locking it out, that shouldn't in theory wouldn’t be working as its using the wrong password!!

Thanks

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

the ad account is an admin account

You need to check the event viewer on a Domain Controller and go to the security log. This is were all logon attempts are logged.

we have two sites, DC1 and DC2, in dc1 we have two domain controllers and in dc2 we have another 2,

where should I check?

rhandelsCommented:
Normally all domain controllers in a domain log all loggon sessions. So take the domain controller of the domain the user is member off (or at least authenticates to)/

You could run "set" command in cmd and search for the logonserver value. This is were your session is authenticated against (the DS that is).

I've got this software from Microsoft called accountlockoutstatus and this tells me that the account was not locked out due to logon attempts:

http://www.microsoft.com/en-us/download/details.aspx?id=15201 

The user tells me that there is only one server he logs into using his domain credentials.

what could be the cause?

Not locked out due to logon attampts?? The only other way an account can be locked out is if it is manually done by the administrator and For as far as i know he or she can only disable the account, not even lock it out manually.

My guess would be that the user added his credentials in some sort of application or maybe his mobile phone, changed his password and now all of a sudden his account is being locked out, to be honest i can't think of anything else.

You could try and check his cached credentials, go to control panel --> Credential manager and check and see if he has "old" credentials stored. If so, delete these..

Agreed. There are only two ways to have an account locked out and rhandels has mentioned them both.

I still think you should disable the account in AD and then wait for either the user or admin to complain as per my post earlier.

The user that is using that acount should come to you and say where the account is being used.

Thanks

the account could be used by a software, device, etc so disabling it don't make any sense.

There is a good chance that MS Credential Manager has saved the credentials on the end-user's machine. Probably for exchange or a similar service (failed logon attempts to exchange or Office 365 will also lock the account out)

On the users' machine, log on to the user's profile, then Go to Control Panel -> Credential Manager and clear any entries that contain the credentials for the account which is being locked out (Including Outlook credentials).

Confirm with the user that this is the only device where their credentials are used. If there is another device, check that as well.

You state 'the account could be used by a software, device, etc. so disabling it don't make any sense. '. You have already stated that the account is used by one admin but that admin cannot help you identify what is causing the lock out.

I and other exports have explained the two possible scenarios as to why an AD account can be locked out.

My suggestions of disabling the account is what I would do to identify where the lock out is occurring.

To me that does make sense. If it is a software, device then as once you disable the account it should be come apparent very quickly which system or device is locking it out.

It’s also worth noting, whatever is locking the account - it’s likely not working hence the lock outs :-)

Thanks
