***Error: The syntax of the domain name, %1, is incorrect. DNS names may contain letters (a-z, A-Z), numbers (0-9), and hyphens, but  no spaces. Periods (.) are used to separate domains. Each domain label can  be no longer than %2!d! bytes. You may not have every label be a number. Example: domain-1.microsoft.com.
