SourceDHCP
DescriptionThe class name is already in use or the class information is already in use.
Event InformationCause:
Currently, the user class option field permits only one ASCII text string to be used for identifying clients. This means each client computer can only be identified as a member of a single user class by the DHCP server. If you need to, you can use additional user classes and make new hybrids from your other user classes.

Resolution:
Check to see that the class name is correctly configured at either the server, scope, client, or class level.
