Servers with underscoures in the names


Is it correct that you shouldnt have a DNS record with an underscoure in the name.  i.e SERVER_TWO.abc.com, so therefore best practice would be not to have servers with underscoures in the names.

actually that is incorrect:

underscores ('_') are not valid in DNS hostnames per RFC 952 and RFC 1123 but are now valid per RFC 2181

MS DNS will support this, but other implementations may not.

You are best NOT to use them to be certain nothing breaks.
