Why do I have user accounts locking out now for no reason

Do you have any processes that log on as a user automatically?

They dont have blackberrys or such like that havent had thier passwords updated and are automatically checking mail?

Can you recreate that users again and then check ,also check any license related issue...

No processes or BB as for the event ID 529 I have a few of these in the security logs but not pertaining to these particular users. BTW licensing is fine or at least appears that way.

What other policies do you have set up?

Did their passwords expire and they were not prompted to change their passwords??

ChiefIT: There is nothing out of the ordinary changed other than the migration. Since that I have had these accounts locking. For example I can unlock a password and have a user attempt logging on, and without making any errors in typing it prompts the user that their account is locked. And it is.

It may be the level of protocol you are trying to authenticate with in exchange:

Your server may be set up to strictly authenticate using Kerberos. I think there are methods to upgrade the authentication of exchange server services to kerberos only.

You would want to use kerberos as the gross vulnerabilities of NTLMhash is something you don't want.

This user does have a second PC and was logged on. I have had him logoff and back on. It should take much longer than an hour to test as I would hear from him every hour. AHHH!

Thanks!! What a relief.
