Question : Delayed Password Lockout on Other Sites in Active Directory

I have an issue where we have various sites setup with Domain Controllers; We have been having an issue where the account may be locked out in the main office, I unlock it, but it doesn't replicate the clearing of the lockout which is causing me to connect to that local DC to clear the lockout. Any ideas why it may not be working?

Answer : Delayed Password Lockout on Other Sites in Active Directory

You'll want to review your site configuration.  If you are still using the Inter-site transport - "DEFAULTIPSITELINK", you are probably syncing about every 15 minutes, so unlocking an account will be propagated in about fifteen minutes.
