Last Updated: 3/28/2017

SYNOPSIS

Gets policies for query resolution from a DNS server.

SYNTAX

Server (Default)

Get-DnsServerQueryResolutionPolicy [[-Name] <String>] [-ComputerName <String>] [-CimSession <CimSession[]>]
 [-ThrottleLimit <Int32>] [-AsJob] [<CommonParameters>]

Zone

Get-DnsServerQueryResolutionPolicy [[-Name] <String>] [-ComputerName <String>] [-ZoneName] <String>
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [<CommonParameters>]

DESCRIPTION

The Get-DnsServerQueryResolutionPolicy cmdlet gets policies for query resolution from a Domain Name System (DNS) server. Specify a zone by name to get zone level policies. If you do not specify a zone, this cmdlet gets server level policies.

EXAMPLES

Example 1: Get all zone level policies

PS C:\> Get-DnsServerQueryResolutionPolicy -ZoneName "contoso.com" | Format-List *

This command gets all the zone level policies for the zone named contoso.com. The command uses the Format-List cmdlet to control the appearance of the output. For more information, type Get-Help Format-List.

Example 2: Get a specific zone level policy

PS C:\> Get-DnsServerQueryResolutionPolicy -Name "NorthAmericaPolicy" -ZoneName "contoso.com" | Format-List *
Action                : Allow
AppliesOn             : QueryProcessing
Condition             : And
Content               : {DnsServerPolicyContent}
Criteria              : {DnsServerPolicyCriteria}
IsEnabled             : True
Level                 : Zone
Name                  : NorthAmericaPolicy
ProcessingOrder       : 1
ZoneName              : contoso.com
PSComputerName        : 
CimClass              : root/Microsoft/Windows/DNS:DnsServerPolicy
CimInstanceProperties : {Action, AppliesOn, Condition, Content...} 
CimSystemProperties   : Microsoft.Management.Infrastructure.CimSystemProperties

This command gets the zone level policy named NorthAmericaPolicy in the domain named contoso.com.

CimSystemProperties   : Microsoft.Management.Infrastructure.CimSystemProperties

The first command gets configuration settings for the current DNS server by using Get-DnsServer cmdlet, and then stores those values in the $DnsServer variable.

The second command passes the ServerPolicies property of each object stored in $DnsServer to Format-List by using the pipeline operator. This example displays both server level and zone level policies.

Example 6: Display the criteria in a DNS policy

PS C:\> $Policy = Get-DnsServerQueryResolutionPolicy -Name "SamplePolicy" -ZoneName "contoso.com"
PS C:\> $Policy.Criteria

The first command gets a policy object, and then stores it in the $Policy variable.

The second command displays the CriteriaType and Criteria in $Policy.

PARAMETERS

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type: SwitchParameter
Parameter Sets: (All)

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-CimSession

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None

Required: False
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
