How do I run New-DfsnRoot remotely

Question

I am trying to build a Windows Server 2019 DFS remotely. My client PC is Windows 10.

First I create a folder and a share remotely. All is okay.

Then I do this from my client PC

$cimSession = New-CimSession -ComputerName "dfs.MYDOMAIN"
New-DfsnRoot -Path "\\MYDOMAIN\DfsnRoot" -TargetPath "\\dfs.MYDOMAIN\DfsnRoot" -Type DomainV2 -EnableSiteCosting $true -CimSession $cimSession
New-DfsnFolder -Path "\\MYDOMAIN\DfsnRoot\ShareName" -State Online -TargetPath "\\FILESERVER\ShareName" -ReferralPriorityClass globalhigh -CimSession $cimSession

But it fails with this

New-DfsnRoot : 110
At C:\Applications\Powershell\CreateShare.ps1:40 char:5
+     New-DfsnRoot -Path "\\MYDOMAIN\DfsnRoot" -TargetPath "\\dfs.alo ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (MSFT_DFSNamespace:ROOT\Microsoft\...FT_DFSNamespace) [New-DfsnRoot], CimException
    + FullyQualifiedErrorId : MI RESULT 110,New-DfsnRoot
    + PSComputerName        : dfs.MYDOMAIN

New-DfsnFolder : 80
At C:\Applications\Powershell\CreateShare.ps1:41 char:5
+     New-DfsnFolder -Path "\\MYDOMAIN\DfsnRoot\ShareName" -State On ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (MSFT_DfsNamespaceFolder:Root\Microsoft\...NamespaceFolder) [New-DfsnFolder], CimException
    + FullyQualifiedErrorId : MI RESULT 80,New-DfsnFolder
    + PSComputerName        : dfs.MYDOMAIN

I first thought it was the remote connection but since I can create the share and folder remotely that should be fine.

If I run this command directly on the dfs server it works just fine.

New-DfsnRoot -Path "\\MYDOMAIN\DfsnRoot" -TargetPath "\\dfs.MYDOMAIN\DfsnRoot" -Type DomainV2 -EnableSiteCosting $true

And actually I can run this after (remotely) with no issues

New-DfsnFolder -Path "\\MYDOMAIN\DfsnRoot\ShareName" -State Online -TargetPath "\\FILESERVER\ShareName" -ReferralPriorityClass globalhigh -CimSession $cimSession

It seems like there is an issue with New-DfsnRoot command and running that remotely

The error in the command indicates 'could not be found', and the output error you're putting shows that the text in the script was

\MYDOMAIN\$DfsnRoot

Note the $, indicating what seems like it should have been a variable but the string wasn't put together properly. Are you sure that the snippet you put in your question matches exactly the script you're having issues with?

I just pasted a bit wrong - I have redone the test without variables. Still same result. – Anders Sep 06 '19 at 17:06
My bad, I should have added this as a comment. I can look further and see what else I find. – Philippe Haussmann Sep 06 '19 at 23:36

I figured it out.

When you run the New-DfsnRoot command you should run it local and not remotely. The New-DfsnFolder should still run remotely. Working script looks like this.

$cimSession = New-CimSession -ComputerName "dfs.MYDOMAIN"
New-DfsnRoot -Path "\\MYDOMAIN\DfsnRoot" -TargetPath "\\dfs.MYDOMAIN\DfsnRoot" -Type DomainV2 -EnableSiteCosting $true
New-DfsnFolder -Path "\\MYDOMAIN\DfsnRoot\ShareName" -State Online -TargetPath "\\FILESERVER\ShareName" -ReferralPriorityClass globalhigh -CimSession $cimSession
