My company is developing new naming scheme but we are unsure how many
characters to use for machine names. We are going to be running mixed 2000
and 2003 AD. Are underscores and dashes alowed?

Thanks in advance, George
 
Both can be used by Windows 2000\2003 DNS but it will make your life easier
if you stick to the standard DNS conventions of only using dashes (and
letters and numbers).

If you are running non-Microsoft DNS then you will definitely not be able to
use underscores. MS DNS is a little less strict on the RFC rules. The
general advice: don't use underscores.
 
Hello George,

It is recommended that you use only Internet-standard characters in the
computer name. The standard characters are the numbers from 0 through 9,
uppercase and lowercase letters from A through Z, and the hyphen (-)
character. Computer names cannot consist entirely of numbers.

If you are using DNS A hierarchical, distributed database that contains
mappings of DNS domain names to various types of data, such as IP
addresses. DNS enables the location of computers and services by
user-friendly names, and it also enables the discovery of other information
stored in the database.on your network, you can use a wider variety of
characters, including Unicode characters and other nonstandard characters,
such as the ampersand (&). Using nonstandard characters may affect the
ability of non-Microsoft software to operate on your network.

The maximum length for a computer name is 63 bytes. If the name is longer
than 15 bytes (15 characters in most languages, 7 characters in some),
computers running Windows NT Server 4.0 and earlier will recognize this
computer by the first 15 bytes of the name only. In addition, there are
additional configuration steps for a name that is longer than 15 bytes

Thanks,

That depends, actually. :-) (I agree with the rest, BTW.)
