SYMPTOMS
When you modify the membership of a Microsoft Exchange Server 5.5 distribution list that has hidden members, those membership changes may be lost. For example, if you remove members or add members, those changes may be lost.

Additionally, you experience the following symptoms in the Active Directory directory service:
 * The distribution group that corresponds to this Exchange Server 5.5 distribution list has the msExchALObjectVersion attribute incremented very frequently.

Note This attribute may be incremented up to one time every minute.
 * If you stop the Recipient Update Service for the domain where you experience this problem, you no longer experience these symptoms



CAUSE
This problem occurs if all the following conditions are true:
 * You have a parent domain such as ..
 * You have a child domain for that parent domain, such as . ..
 * Exchange Server 5.5 is running on a computer in the child domain.
 * You install the Active Directory Connector in the child domain to replicate distribution list information to the parent domain and to replicate distribution group information from the parent domain to Exchange Server 5.5.
 * You install Exchange Server 2003 in the child domain, and then you create a new Recipient Update Service that points to the parent domain.

Note This Recipient Update Service stamps distribution groups that are created in the parent domain.
 * You add users to an Exchange Server 5.5 distribution list that has hidden members, or you remove users from such a distribution list.

In this scenario, the Recipient Update Service repeatedly stamps distribution groups that contain hidden members. This causes the msExchALObjectVersion attribute to be updated very frequently. In this scenario, new membership modifications to a distribution list in Exchange Server 5.5 may be overwritten by previous membership information from the corresponding distribution group in Active Directory. This behavior occurs when the Active Directory Connector connection agreement replicates this information to Exchange Server 5.5.
