Underscore Not Supported in Intel® AMT Hostnames

Intel® AMT hostnames are most often set to match the Guest Operating System (OS) hostname. In some production environments, IT operations are using an underscore "_" in their guest OS naming convention. This is viewed as an illegal name by Intel® AMT and according to RFC952.

Please refer to RFC952 (http://www.faqs.org/rfcs/rfc952.html) for industry standards on naming conventions. As quoted from that document:

"A 'name' (Net, Host, Gateway, or Domain name) is a text string up to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus sign (-), and period (.). Note that periods are only allowed when they serve to delimit components of 'domain style names'… No blank or space characters are permitted as part of a name. No distinction is made between upper and lower case. The first character must be an alpha character. The last character must not be a minus sign or period… Single character names or nicknames are not allowed."

Similar naming specifications or limitations can be found with DNS records, hostnames, mail server setups, etc.
