SYMPTOMS
The Microsoft Exchange Server 2003 Recipient Update Service continually updates some recipients or public folders with what appear to be random SMTP proxy addresses. Additionally, you experience the following symptoms:
 * The number of SMTP proxy addresses may continue to increase.
 * The performance of Windows domain controllers may decrease.
 * The processor usage of Lsass.exe may be close to 100%.



CAUSE
Because of particular configurations of recipient policies, the Recipient Update Service may not be able to recognize addresses as valid. Therefore, the Recipient Update Service will continue to stamp the addresses with additional random SMTP proxy addresses. The most common cause is a change to the default recipient policy, such as using %g.%s wildcards instead of %m wildcards. If %g.%s wildcards are used, non-user objects that do not use the given name and surname attributes, such as resource mailboxes and public folders, are evaluated incorrectly when the recipient policy is applied.
