Configure Exchange 2007 Preferred Domain Controller Settings

In some managed Exchange 2007 environments, the preferred Domain Controller used by Exchange 2007 servers is different to the Domain Controller used by the Active Directory connector. As a result, the Active Directory replication latency can introduce mailbox creation failure. To prevent mailbox creation failure, configure the Exchange Server so that it communicates directly with the Active Directory connector preferred Domain Controller.

To resolve the issue, we recommend that you set the ADS_E2K_SEND_DC system environment variable on the on IM_CCS computer to 1.

Note: By default the value of the ADS_E2K_SEND_DC system environment variable value is 0.

Note: This setting is only available for an Exchange 2007 environment. The setting is not available for Exchange 2010 environments.
