SYMPTOMS

In a Microsoft Windows 2000 forest that contains more than 800 domain controllers, the Exchange 2000 Recipient Update Service may not run properly, and may log an error message that is similar to the following:
Event Type: Error
Event Source: MSADC
Event Category: LDAP Operations
Event ID: 8270
Date: 12/3/2001
Time: 4:33:51 AM
User: N/A
Computer: PARSIFAL
Description:
LDAP returned the error [b] Administration Limit Exceeded when importing the transaction dn: CN=Recipient Update Service (DOMAIN),CN=Recipient Update Services,CN=Address Lists Container,CN=Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=com changetype: Modify msExchServer1HighestUSN:1696357 msExchServer1HighestUSNVector:SERVER1:1868357 : SERVER2:2097926 : SERVER3:1696357 : SERVER4:3289482 : SERVER5:3493342 : SERVER6:3523081 : ...
NOTE: The event description contains all of the domain controller names (more than 800 names).

CAUSE

This problem can occur because there is an architectural limit of approximately 800 values (that are not distinguished name-linked) in a multivalued attribute in the Windows 2000 Active Directory. When there are more than 800 domain controllers, the Recipient Update Service attempts to update the msExchServer1HighestUSNVector attribute with the name and update sequence number (USN) number of each domain controller, which does not work because of the architectural limitation.

RESOLUTION

To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
