To change the name-checking method used by the DNS server

Click the Advanced tab.
In the Name checking list, select Strict RFC (ANSI), Non RFC (ANSI), Multibyte (UTF8), or All names.
To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
To open DNS, click Start, click Control Panel, double-click Administrative Tools, and then double-click DNS.
The DNS Server service supports different possible methods for checking the names it receives and processes during normal operations:
Strict RFC (ANSI) This method strictly enforces RFC-compliant naming rules for all DNS names that the server processes. Names that are not RFC-compliant are treated as erred data by the server.
Non RFC (ANSI) This method allows names that are not RFC-compliant to be used with the DNS server, such as names that use ASCII characters but are not compliant with RFC host naming requirements.
Multibyte (UTF8) This method allows names that use the Unicode 8-bit translation encoding scheme, which is a proposed RFC draft, to be used with the DNS server.
By default, the server uses Multibyte (UTF8) to check names.
All names Allows Non RFC (ANSI), Strict RFC (ANSI), and Multibyte (UTF8) naming conventions.
Information about functional differences
- Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
