EXPLANATION:
This event indicates that the Active Directory Connector (ADC) could not convert the domain name of an object and therefore will not be able to replicate the object to the target directory. This could occur, for example, if an object has a domain name formatted incorrectly.
USER ACTION:
In most cases, this may never be seen. If this event is seen, and if there are no other symptoms of a problem, it can be safely ignored.
