The Directory Service Access component, the Recipient Update Service component, and the Categorizer component do not time out as expected in Exchange 2000 Server or in Exchange Server 2003

The following components in Microsoft Exchange 2000 Server and in Microsoft Exchanger Server 2003 do not time out within the expected time limit when a delay occurs:

• Directory Service Access (DSAccess)
• Recipient Update Service (RUS)
• Categorizer

When they time out, the stores on Exchange Server dismount.

This problem occurs because the timeout value for these components is incorrectly multiplied by 1,000 when the ldap_set_option command is used to set the LDAP_OPT_SEND_TIMEOUT Lightweight Directory Access Protocol (LDAP) option. The ldap_set_option command is called with a value in milliseconds. However, a value in seconds is expected.

The LDAP_OPT_SEND_TIMEOUT option is expected to set the limit on the number of seconds that the local LDAP client will wait while trying to send data to a remote computer. If the send operation is not completed before the timeout period expires, the LDAP call will fail with an LDAP_TIMEOUT error code.

The default timeout value for Directory Service Access is 30. This value is incorrectly multiplied by 1,000 and is set to the value of 30,000 seconds. 30,000 seconds equal 8 hours and 20 minutes.

The default timeout value for Recipient Update Service is 180. This value is incorrectly multiplied by 1,000 and is set to the value of 180,000 seconds. 180,000 seconds equal 50 hours.

The default timeout value for Categorizer is 30. This value is incorrectly multiplied by 1000 and is set to the value of 30,000 seconds. 30,000 seconds equal 8 hours and 20 minutes.
