How to prevent the ADC from overwriting the CN with the Exchange 5.5 Display Name

When a connection agreement is executed, existing accounts in AD may get renamed with the display name of their corresponding Exchange 5.5 mailboxes.  Even after the AD account is renamed manually, it will be overwritten the next time the Connection Agreement runs an update.  The following procedure is a workaround to prevent the overwrite from occurring, once the migrated account is renamed.

Use this procedure with caution.

  1. Start ADSI Edit. (ADSI Edit is included in the Microsoft Windows 2000 support tools on the Windows 2000 CD-ROM.)
  2. Expand the following Configuration Container:
    CN=Configuration, CN=Services, CN=Microsoft Exchange, CN=Active Directory Connections.
  3. Right-click the Connection Agreement you want to modify, and select Properties.
  4. Ensure Select which properties to view is set to Optional.
  5. In the Select a property to view box, click the down arrow, and then click msExchServer1Flags.
  6. In the Edit Attribute box, type "2". 
  7. Click on Set
  8. Click on OK.
