Add-DAClientDnsConfiguration

Last Updated: 4/3/2017

SYNOPSIS

Adds the specified DNS suffix, DNS server addresses, or proxy server set to the Name Resolution Policy Table (NRPT).

SYNTAX

Add-DAClientDnsConfiguration [[-DnsIPAddress] <String[]>] [-DnsSuffix] <String> [-ProxyServer <String>]
 [-ComputerName <String>] [-PassThru] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf]
 [-Confirm] [<CommonParameters>]

DESCRIPTION

The Add-DAClientDNSConfiguration cmdlet adds the specified DNS suffix, DNS server addresses, or proxy server set to the Name Resolution Policy Table (NRPT). When a DNS suffix is specified, but no servers are specified, it is treated as a NRPT exemption entry.

In a multi-domain deployment, when an NRPT entry that consists of DNS suffix, proxy server and DNS IP addresses is added to the NRPT table the settings are added to all the DirectAccess (DA) client Group Policy Objects (GPOs) in different domains. In multi-site deployment with firstref_client_7 clients, the added entries are added to both the Windows® 8 client GPOs and Windows® 7 client GPOs.

The NRPT configuration is applicable globally, to the entire DA deployment and therefore is not impacted by multi-site deployment.

EXAMPLES

EXAMPLE 1

PS C:\> Add-DAClientDNSConfiguration -DnsSuffix contoso.com -DnsIPAddress 2006:2005:1::2 -PassThru
Comment                          : 
DirectAccessDnsServers           : {2006:2005:1::2} 
DirectAccessEnabled              : True 
DirectAccessProxyName            : 
DirectAccessProxyType            : Direct 
DirectAccessQueryIPsecEncryption : None 
DirectAccessQueryIPsecRequired   : False 
DisplayName                      :

Name                             : DA-{64329e4f-bd27-4d27-9553-6ed6880fa2a5}

Version                          : 1

This example will add an entry for contoso.com into the NRPT which will result in all the DNS queries for the suffix contoso.com to be sent to 2006:2005:1::2 server.

EXAMPLE 2

PS C:\>Add-DAClientDNSConfiguration -DnsSuffix corp.contoso.com -PassThru
Comment                          : 
DirectAccessDnsServers           :

NameEncoding                     : 
NameServers                      : 
Namespace                        : {corp.contoso.com} 
Version                          : 1

This example will add an exempt entry for corp.contoso.com in the NRPT which will result in DNS queries for the suffix corp.contoso.com to not go to a DNS server in the corporate network for resolution.

There are some names that need to be treated differently from all others with regards to name resolution; these names must not be resolved using intranet DNS servers. To ensure that these names are resolved with interface-configured DNS servers, these must added as NRPT exemptions.

There are several names that should be included on the exemption list - but the most important one is the name of the Network Location Server. This prevents the DA client from being able to connect to the NLS server when the server is off network and therefore prevents it from mistakenly thinking that it is on the corporate network.
