Set-DfsnFolder

Changes settings for a DFS namespace folder.

Syntax

Parameter Set: SetNamespaceFolder4
Set-DfsnFolder [-Path] <String> [[-EnableInsiteReferrals] <Boolean> ] [[-EnableTargetFailback] <Boolean> ] [[-State] <State> ] [[-TimeToLiveSec] <UInt32> ] [[-Description] <String> ] [-AsJob] [-CimSession <CimSession[]> ] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Set-DfsnFolder cmdlet changes settings for a Distributed File System (DFS) namespace folder.

A DFS namespace folder has one or more folder targets that are shared folders on computers. When a client attempts to connect to a folder, the DFS namespace server provides a list of folder targets, called referrals. The server determines the order for referrals and clients attempt to connect to a folder target in the order that the server provides.

You can use this cmdlet to enable or disable the following settings:

-- In-site referrals.
-- Target failback.

You can also add or change a descriptive comment, change the state of the DFS namespace, or set the Time to Live (TTL) interval for referrals.

For more information about DFS namespaces, see Overview of DFS Namespaces (http://technet.microsoft.com/library/cc730736) on TechNet.

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.

-EnableInsiteReferrals<Boolean>

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, a 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.

-EnableTargetFailback<Boolean>

Indicates whether a DFS namespace uses target failback. If a client attempts to access target link 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 use the preferred server.
