What's New in DNS Client in Windows 8

Published: June 24, 2013

Updated: June 24, 2013

Applies To: Windows 8, Windows Server 2012

This topic provides information about new and changed functionality in the DNS Client service in Windows 8. For an overview of DNS Server service and the DNS Client service, and links to review changes in other versions of Windows, see What's New in DNS.

Changes to the DNS Client service in Windows 8 are also present in computers running Windows Server 2012.

New functionality in DNS Client for Windows 8 includes the following.


Feature/functionality New or improved Description

Link-local multicast name resolution (LLMNR)


Outbound LLMNR queries are not sent to mobile broadband and VPN interfaces.

Network basic input/output system (NETBIOS)


Outbound NETBIOS queries are not sent to mobile broadband interfaces.

LLMNR timeout


The LLMNR query timeout has been increased to 410 msec for the 1st retry and 410 msec for the 2nd retry. The total timeout value is now 820 msec instead of 300 msec. This change is to solve a problem with computers in power saving mode. LLMNR and NETBIOS queries are also issued in parallel, improving response times for all queries.

Parallel queries


LLMNR and NETBIOS are issued in parallel and optimized for IPv4 and IPv6 queries.

Binding order optimization


Interfaces are divided into networks to send parallel DNS queries and prefer binding order responses.

Protocol reordering


If a specific interface is hijacking DNS names, then for flat names on those networks LLMNR and NETBIOS queries are sent in parallel with DNS queries and the LLMNR or NETBIOS response is preferred.

Asynchronous DNS cache


All the queries in DNS cache service are asynchronous and response timing is optimized.
