User keeps getting locked out

Hi Folks,

Using Windows 2000 Server Standard.
 
Clients use Windows XP.

I have a user who logs onto our domain succesfully, opens up his outlook e-mails which is connected to our exchange server succesfully. The user can connect to our SQL server through our ERP package succesfully and everything is fine.

Give it an hour or so and the user cannot log in to the SQL server, the exchange server or any of the shared folders on the network. It just prompts him to enter a username and password each time. When he enters his username and password it is not accepted and i have to get him to log out and then a have to unlock his account in Active Directory.

The user can then log back in to all his applications again.

Any ideas why  Windows would keep automatically locking this user out?

Thanks in advance,

Baikie

ENable security auditing on the domain controller.. and the client machine from where the user is trying to logon. This might be serious. Security auditing on the dc will let us know how many times the logon hi happening and when it fails etc.. let me know what you have ..

Hi,

Thanks for the reply.

It turns out the user had logged onto terminal server, disconnected, then came into the office and reset his password to a new one. Therefore he was still logged onto terminal server with an old password. One of the services he was using terminal services for uses windows authentcation so this was continually trying to authenticate then eventually locking the user out.

Anyway, problem solved. Thanks for the reply again.

Take it easy.
