Description

Examples

Example 1: Create a Windows Server 2008 mode domain DFS namespace

New-DfsnRoot -TargetPath '\\Contoso-FS\AccountingResources' -Type 'DomainV2' -Path '\\Contoso\AccountingResources'

Example 2: Create a stand-alone DFS namespace

New-DfsnRoot -TargetPath '\\Contoso-FS\Software' -Type 'Standalone' -EnableSiteCosting -Path '\\Contoso\Software'

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.

Parameter properties

Parameter sets

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Parameter properties

Parameter sets

-Confirm

Prompts you for confirmation before running the cmdlet.

Parameter properties

Parameter sets

-Description

Specifies a description for a DFS namespace.

Parameter properties

Parameter sets

-EnableAccessBasedEnumeration

Indicates whether a DFS namespace uses access-based enumeration. If this value is $true, a DFS namespace server shows a user only the files and folders that the user can access.

Parameter properties

Parameter sets

-EnableInsiteReferrals

Indicates whether a DFS namespace server provides a client only with referrals that are in the same site as the client. If this value is $true, the DFS namespace server provides only in-site referrals. If this value is $false, the DFS namespace server provides in-site referrals first, then other referrals.

Parameter properties

Parameter sets

-EnableRootScalability

Indicates whether a DFS namespace uses root scalability mode. If this value is $true, DFS namespace servers connect to the nearest domain controllers for periodic namespace updates. If this value is $false, the servers connect to the primary domain controller (PDC) emulator.

Parameter properties

Parameter sets

-EnableSiteCosting

Indicates whether a DFS namespace uses cost-based selection. If a client cannot access a folder target in-site, a DFS namespace server selects the least resource intensive alternative. If you provide a value of $true for this parameter, DFS namespace favors high-speed links over wide area network (WAN) links.

Parameter properties

Parameter sets

-EnableTargetFailback

Indicates whether a DFS namespace uses target failback. If a client attempts to access a target on a server and that server is not available, the client fails over to another referral. If this value is $true, once the first server becomes available again, the client fails back to the first server. If this value is $false, the DFS namespace server does not require the client to fail back to the preferred server.

Parameter properties

Parameter sets

-GrantAdminAccounts

Specifies an array of accounts. This cmdlet grants management permissions for the DFS namespace to the users and user groups specified. Users can add, remove, and modify namespace folders and folder targets.

Parameter properties

Parameter sets

-Path

Specifies a path for the root of a DFS namespace. This path must be unique. This path cannot be the name of an existing DFS namespace.

Parameter properties

Parameter sets

-ReferralPriorityClass

Specifies the target priority class for a DFS namespace root. Target priority offers you the ability to classify and rank in-site targets. You can specify targets to receive the highest or lowest preference, and you can divide the remaining targets based on their site cost for a DFS client to connect to them. The acceptable values for this parameter are:

• GlobalHigh - The highest priority class for a DFS target. Targets assigned this class receive global preference.
• SiteCostHigh - The highest site cost priority class for a DFS target. Targets assigned this class receive the most preference among targets of the same site cost for a given DFS client.
• SiteCostNormal - The middle or normal site cost priority class for a DFS target.
• SiteCostLow - The lowest site cost priority class for a DFS target. Targets assigned this class receive the least preference among targets of the same site cost for a given DFS client.
• GlobalLow - The lowest level of priority class for a DFS target. Targets assigned this class receive the least preference globally.

Parameter properties

Parameter sets

-ReferralPriorityRank

Specifies the priority rank, as an integer, for a root target of the DFS namespace. Lower values have greater preference. A value of zero (0) is the greatest preference.

Parameter properties

Parameter sets

-State

Specifies the state of the DFS namespace root. The acceptable values for this parameter are:

• Online
• Offline

Clients do not receive referrals for a DFS namespace folder that is offline. If you set a namespace root to a value of Offline, the entire namespace becomes inaccessible.

Parameter properties

Parameter sets

-TargetPath

Specifies a path for a root target of the DFS namespace.

Parameter properties

Parameter sets

-TargetState

Specifies the state of the DFS namespace root target. The acceptable values for this parameter are:

• Online
• Offline

Clients do not receive referrals for a DFS namespace folder target that is Offline.

Parameter properties

Parameter sets

-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.

Parameter properties

Parameter sets

-TimeToLiveSec

Specifies a TTL interval, in seconds, for referrals. Clients store referrals to root targets for this length of time. The default TTL interval for root referrals is 300 seconds.

Parameter properties

Parameter sets

-Type

Specifies the type of a DFS namespace as a Type object. The acceptable values for this parameter are:

• Standalone - Specifies a stand-alone namespace.
• DomainV1 - Specifies a Windows 2000 Server mode domain namespace.
• DomainV2 - Specifies a Windows Server 2008 mode domain namespace.

Parameter properties

Parameter sets

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.
