KB-0643: Zonegen returns error: Specified Cast is not valid

Authentication Service ,

When running Zonegen, it is unsuccessful and you see the message:
System.InvalidCastException: Specified cast is not valid


This problem will occur if the inzone (the source Zone) contains a user that no longer exists in AD or contains an AD user of type “InetOrgPerson”.


Remove the above mentioned AD users from inzone and rerun Zonegen
