Powershell script to get a list of DFS folder targets for all DFS folders under a defined path and test if those paths are valid from the location running the script.

Compare-DFStoFolders.ps1

$Servers = @("SERVER01","SERVER02","SERVER03")

$FolderPaths = $Servers | foreach {
    Get-ChildItem "\\$_\DFSShare$"
} | Sort Path

$FolderPaths | Export-Csv "FolderPaths-$(Get-Date -format yyyy-MM-dd).csv" -NoTypeInformation

$TestPaths = (($FolderPaths).FullName | Sort-Object).Trimend('\')
$DFSPaths = ((Import-CSV "DFS-$(Get-Date -format yyyy-MM-dd).csv").TargetPath | Where-Object {($_ -ilike "*SERVER*") | Sort-Object).Trimend('\')

$TestPaths | Where-Object {$DFSPaths -notcontains $_}

Get-DFSFolderTargets.ps1

[CmdletBinding()] 
param(
    $DFSPath #Example:= '\\example.com\folder\*\whatever'
)

Write-Progress "Getting all DFS folders for $DFSPath (this can take a very long time)" -PercentComplete -1
$DFSTree = Get-DfsnFolder $DFSPath

$i = 1
$DFSTree | ForEach-Object{
    Write-Progress "Getting DFS Folder Targets for $($_.Path)" -PercentComplete (($i / $DFSTree.Count) *100)
    
    $DFSTarget = Get-DfsnFolderTarget $_.Path | Select Path,TargetPath,State

    $Result = [ordered]@{
        Path = $DFSTarget.Path
        TargetPath = $DFSTarget.TargetPath
        State = $DFSTarget.State
        "ValidFrom_$Env:ComputerName" = Test-Path $DFSTarget.Path
    }
    
    New-Object PSObject -Property $Result
    $i++

} | Sort Path | Export-Csv "DFS-$(Get-Date -format yyyy-MM-dd).csv" -NoTypeInformation

Thanks for this. Very helpful.

if my dfs folder has 3 path (more than one) I get "System.Object[]","System.Object[]","System.Object[]","System.Object[]"

log:
"\\mydomain\dfs1\folderA","\\server5\share$\folderA","Online","True"
"\\mydomain\dfs1\folderB","\\server5\share$\folderB","Online","True"
"System.Object[]","System.Object[]","System.Object[]","System.Object[]"
"\\mydomain\dfs1\folderD","\\server7\share$\folderD","Online","True"
"System.Object[]","System.Object[]","System.Object[]","System.Object[]"
"System.Object[]","System.Object[]","System.Object[]","System.Object[]"
"\\mydomain\dfs1\folderG","\\server5\share$\folderG","Online","True"
"\\mydomain\dfs1\folderH","\\server6\share$\folderH","Online","True"

example:
Get-DfsnFolderTarget \\mydomain\dfs1\folderC
Path TargetPath State ReferralPriorityClass ReferralPriorityRank

\\mydomain\dfs1\folderC \\server5\share$\folderC Online sitecost-normal 0
\\mydomain\dfs1\folderC \\server6\share$\folderC Online sitecost-normal 0
\\mydomain\dfs1\folderC \\server7\share$\folderC Online sitecost-normal 0

To address the issue reported by @kamiltitera I forked the gist and made the script iterate through each destination when an array is returned. Unfortunately, gists don't have pull request support, so the author @markwragg would need to review the code and see if it is something he wants to manually commit.

The proposed change can be found here: https://gist.github.com/justpowershell/488f8c6936dfb7be8178e337cebaa250

@justpowershell your forked version works like a charm. It should definitely be added to the main script.

@markwragg I see that this has been dormant for a bit, but I just stumbled across it, and hope it might be what I am looking for. I have a large DFS structure, but it is a mess. I am trying to find all of the locations where we have a \home\ and then a user account folder in my structure.

Could I use this for something like that. Basically, we have been going through a lot of turnover and I just got a list of almost 250 users that have left the organization, and I need to remove their home directories, unfortunately, the previous regime didn't believe in using the AD homedirectory field, so I have no clue where the home directories might live, besides, "They are in DFS". Can i use your script to spit out all of the folders in my DFS and filter out the home directories?

app

This script only works for a single target. I fixed it to work with multi-value properties.

[CmdletBinding()]
param(
$DFSPath = '\DFSNamespace*'
)

Write-Progress "Getting all DFS folders for $DFSPath (this can take a very long time)" -PercentComplete -1
$DFSTree = Get-DfsnFolder $DFSPath

$i = 1
$DFSTree | ForEach-Object{
Write-Progress "Getting DFS Folder Targets for $($_.Path)" -PercentComplete (($i / $DFSTree.Count) *100)

$DFSTarget = Get-DfsnFolderTarget $_.Path | Select Path,TargetPath,State

$Result = [ordered]@{
    Path = $DFSTarget.Path
    TargetPath = $DFSTarget.TargetPath
    State = $DFSTarget.State
    "ValidFrom_$Env:ComputerName" = Test-Path $DFSTarget.Path
}

New-Object PSObject -Property $Result
$i++

} | Sort Path | Select @{Name='Path';Expression={[string]::join(";", ($."Path"))}}, @{Name='TargetPath';Expression={[string]::join(";", ($."TargetPath"))}},@{Name='State';Expression={[string]::join(";", ($_."State"))}} | Export-Csv "DFS-$(Get-Date -format yyyy-MM-dd).csv"

I know this is dated...but I thought I'd add what I've done:

Here's what
$namespaces = Get-DfsnRoot -Domain domain.com

foreach ($ns in $namespaces){
#$ns.Path
#Get
$DFSPath = "$($ns.path)*"
$DFSPath
$DFSNFolders = Get-DfsnFolder $DFSPath
foreach($DFSNFolder in $DFSNFolders )
{
$DFSTarget = Get-DfsnFolderTarget $DFSNFolder.Path | Select Path,TargetPath,State
$DFSTarget|Export-Csv "DFS.csv" -NoTypeInformation -Append

}

}

Hi Shackdan,

your Script created an empty file.

Perhaps you don't have access to the DFS namespace.
You can verify by simply running "Get-DfsnRoot -domain [domain.com]"

@JoeAlvis81
For some reason i get empty cells as output shown below:

#TYPE Selected.System.Management.Automation.PSCustomObject
Path	TargetPath	State
		Online
		Online
		Online
		Online
		Online
		Online
		Online
		Online
		Online

This one worked
$namespaces = '\domainns\x*'
foreach ($ns in $namespaces)
{
$DFSNFolders = Get-DfsnFolder -path $ns
foreach($DFSNFolder in $DFSNFolders )
{
$dfs=$DFSNFolder.Path
$DFSTarget = Get-DfsnFolderTarget $DFS | Select Path,TargetPath,State
$DFSTarget|Export-Csv "DFS.csv" -NoTypeInformation -Append
}
}

I get one or more parameter values passed to the method were invalid in the line $DFSNFolders = Get-DfsnFolder -path $ns

Alanmckeon - To fix the error add a \ in the path

$DFSPath = "$($ns.path)*"

Wrote an improved function
