SYMPTOMS
Consider the following scenario. A Windows Server 2003 domain trusts another Windows Server 2003 domain. You log on to a computer in the trusting domain by using a user account in the trusted domain. However, you may receive the following error message after type the correct user name and password:

The system could not log you on. Please make sure your user name and password are correct

Additionally, the following event may be logged in the System log on some domain controllers: Event Type: Error

Event Source: NETLOGON

Event Category: None

Event ID: 3224

Date:

Time:

User: N/A

Computer:

Description:

Changing machine account password for account  failed with the following error:

There are currently no logon servers available to service the logon request.

This problem occurs every 30 days. This problem stops after a complete replication occurs in the domains.



CAUSE
Both domains in a trust relationship share a password. This password is stored in the Trusted Domain Object (TDO) in Active Directory. As part of the account maintenance process, the trusting domain controller changes the password that is stored in the TDO every 30 days. If the changed trust password has not replicated to all domain controllers in an hour, some domain controllers still use the old trust password. Therefore, the authentication fails.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

By default, domain controllers continue to use the old trust password for an hour after the trust password changes. This one-hour period cannot be configured. After you install this hotfix, you can use a registry entry to configure this period according to the network condition. For more information about how to enable this feature, see the &quot;Registry information&quot; section.
