GMS needed to check that an account exists. GMS has been configured to use the Windows authentication service. When GMS attempted to get the name of the Domain Controller the operating system indicated that the information was not available.
In this case, GMS was attempting to get the name of the Domain Controller Undefined in order to verify the account Undefined@Undefined exists and the operating system responded with the error code Undefined.
This is not a problem with GMS. To find out more about the error returned, please check the Knowledge Base for your operating system.
