IT Interview Questions:What could cause the Forwarders and Root Hints to be
grayed out?
What is a "Single Label domain name" and what sort of issues can it cause?
Single-label names consist of a single word like "contoso".
• Single-label
DNS names cannot be registered by using an Internet registrar.
• Client
computers and domain controllers that joined to single
-label domains require
additional configuration to dynamically register DNS records in single-
label DNS zones. •
Client computers and domain controllers may require additional
configuration to resolve DNS queries in single-label DNS zones.
• By default, Windows Server 2003
-based domain members, Windows XP-based domain members,
and Windows 2000-based domain members do not perform dynamic updates to
single-label DNS zones.
• Some server
-based applications are incompatible
with single-label domain names. Application support may not exist in the
initial release of an application, or support may be ropped in a future
release. For example, Microsoft Exchange Server 2007 is not supported in
environments in which single-label DNS is used.
• Some server
-based
applications are incompatible with the domain rename feature that is
supported in Windows Server 2003 domain controllers and in Windows Server
2008 domain controllers. These incompatibilities either block or complicate
the use of the domain rename feature when you try to rename a single-label
DNS name to a fully qualified domain name.
