XADM: Large Number of Recipient Policies Causes Metabase Problem

Article ID: 274550 - View products that this article applies to.

This article was previously published under Q274550

SYMPTOMS

When you configure a large number of recipient policies in Exchange 2000 Server (for example, more than 1,000 policies), Simple Mail Transfer Protocol (SMTP) local domains that are listed in the policies may not be correctly replicated from NTDS to the Microsoft Internet Information Service (IIS) metabase.

CAUSE

This problem can occur because the algorithm that Exchange 2000 currently uses to replicate SMTP local domains that are listed in recipient policies from NTDS to the IIS metabase does not scale for a large number of policies (greater than 1,000) for the following reasons:

Active Directory has a page size restriction of 1,000 entries.
Exchange 2000 (DSAccess) does not read past the first page.
When a recipient policy is deleted, the directory service to metabase (also known as the metabase update service) must reread all policies to determine what should be removed from the metabase. If there are more than 1,000 policies in the system, correct deletions cannot occur.
