The information store may stop responding, and the stores may appear to be dismounted in Exchange 2003 (833907)

The information in this article applies to:

Microsoft Exchange Server 2003 Standard Edition
Microsoft Exchange Server 2003 Enterprise Edition

SYMPTOMS

The information store may stop responding, and the stores may appear to be dismounted in Microsoft Exchange Server 2003. Additionally, the clients cannot connect to the server.

CAUSE

This problem occurs if the DSAccess component incorrectly calculates the time-out value of a Lightweight Directory Access Protocol (LDAP) session. The DSAccess component incorrectly uses milliseconds instead of seconds when it uses the ldap_set_option function to set the LDAP_OPT_SEND_TIMEOUT value.

By default, the value of the LDAP_OPT_SEND_TIMEOUT is 30 seconds. However, the DSAccess component sets the LDAP_OPT_SEND_TIMEOUT value to 30,000 seconds.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server 2003.
