XADM: ADC Cannot Replicate MsexchmasteraccountSID and Generates Event ID 8281 (297356)
The information in this article applies to:
- Microsoft Exchange 2000 Server
This article was previously published under Q297356 SYMPTOMS
During Active Directory Connector (ADC) replication, the following warning may be logged in the application event log:
Event Type: Warning
Event Source: MSADC
Event Category: Replication
Event ID: 8281
Description:
ADC could not replicate the msExchMasterAccountSid to
CN=Brad H1,CN=Users,DC=NT4DOM1,DC=RCPDOM,DC=extest,DC=microsoft,DC=com
because this sid is already on the object
CN=t-bradh1,CN=Users,DC=NT4DOM1,DC=RCPDOM,DC=extest,DC=microsoft,DC=com. (Connection Agreement 'CDC-SITE1' #1444)
CAUSE
This behavior may occur if all of the following conditions are true:
- The end point of the ADC Connection Agreement is not a global catalog server.
-and- - The mailbox that you are replicating already has an existing Active Directory account.
-and- - The mailbox's display name is different from the Active Directory account name.
The ADC renames the user object on the domain controller to the Microsoft Exchange Server 5.5 display name. However, when the uniqueness check for the master account SID is performed against the global catalog server, the name change has not been replicated to the global catalog server. An object with a different distinguished name is found with the same master account security identifier (SID), and therefore the warning is logged.
RESOLUTION
You can safely ignore this warning while you make sure that the two objects listed in the warning are the same object.
WORKAROUND
To work around this issue, modify the ADC Connection Agreement to point to the global catalog server.
