SYMPTOMS
When changes are replicated from Exchange Server 5.5 directory objects to Windows 2000 Active Directory across the Active Directory Connector (ADC), the replication may create new objects instead of modifying the existing Active Directory account that is associated with the mailbox.

You may find the following information in the Ex55-2failed.ldf file:

ADC could not replicate the msExchMasterAccountSid to CN=Winks\, Hank,CN=Users,DC=ACP-INC,DC=LOCAL because this sid is already on the object CN=Hank Winks,OU=ACP,DC=ACP-INC,DC=LOCAL. (Connection Agreement 'Exchange/Windows CA MLC 9-11-00' #2200) For more information, click http://search.support.microsoft.com/search/?adv=1.



CAUSE
This issue can occur if the msExchADCGlobalNames value of the existing Active Directory object is either missing or corrupted.



RESOLUTION
WARNING: If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Exchange 2000 Server, or both. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.

To resolve this issue:
 * 1) Use the Active Directory Administration tool or the Active Directory Service Interface (ADSI) Edit snap-in to copy the msExchADCGlobalNames value from the newly created object to the msExchADCGlobalNames value of the existing object.
 * 2) Verify that the values are identical.
 * 3) Delete the new object.
