I am trying to deploy the SCVMM resource bridge from my VMM server and getting a Import/BIT error during the upload

Question

When running the SCVMM azure arc resource bridge creation, the script fails with an error around the import of an appliance to the VMMLibrary. I have verified I have permissions to create items on the VMMLibrary share.

Initially the BITS services wasn't running which I started manually but still get an error - now a BITS authentication error - and I have confirmed I can do a bits transfer (Start-bitstransfer)

Thanks in advance.

the following is the original error

{

"errorCode": "InvalidEntityError",

"errorResponse": "{\n"message": "VMM Server doesn't have write permission into the specified library share : \\\\AUXXHSTVMM01.hosting.ss\\MSSCVMMLibrary.

** this is the error once I started BITs

Import-SCLibraryPhysicalResource : The BITS client job failed to succeed for 'C:\Temp\SW_DVD5_Sys_Ctr_DataCenter_Core_2025_24H2_MultiLang_OpsMgr_MLF_X23-81907.ISO' when attempting 'Start-BitsTransfer' resource with

following error: HTTP status 401: The requested resource requires user authentication.

Restart BITS service and try the operation again. Also make sure that the client has permissions on the source and the destination.

Hi Macca
Welcome to Microsoft Q&A platform, Thanks for asking question here...!
Step-by-step process to resolve the SCVMM Azure Arc Resource Bridge creation error that your experiencing.
1.Log in to the VMM server with your SCVMM operations account.
2.Navigate to the library share: \AUXXHSTVMM01.hosting.ss\MSSCVMMLibrary.
3.Right-click the folder, select Properties, and open the Security tab.
4.Ensure your user account has Full Control permissions.
5.Open PowerShell and run the following command to create a test file:

New-Item -Path "\\AUXXHSTVMM01.hosting.ss\MSSCVMMLibrary\testfile.txt" -ItemType File

6.In PowerShell, execute the following command to test BITS functionality:

Start-BitsTransfer -Source "C:\Temp\SW_DVD5_Sys_Ctr_DataCenter_Core_2025_24H2_MultiLang_OpsMgr_MLF_X23-81907.ISO" -Destination "\\AUXXHSTVMM01.hosting.ss\MSSCVMMLibrary\testfile.iso"

7.Check that no firewall rules are blocking access to the library share on both local and network firewalls.
8.Verify that the proxy settings are correctly configured for BITS transfers if your environment uses a proxy.
9. Run Diagnostic commands open PowerShell and run the following commands to validate library share access and permissions:

$driveinfo = Get-WmiObject Win32_OperatingSystem
$SystemDrive = $driveinfo.SystemDrive
$localPath = "$SystemDrive\ProgramData\libpath-test"
New-Item -ItemType Directory -Path $localPath | Out-Null
$filename = "testfile.ps1"
New-Item -Name $filename -Value "test file copy" -Path $localPath | Out-Null
# Attempt to import the test file back into the library
Import-SCLibraryPhysicalResource -SourcePath "$localPath\$filename" -SharePath "\\AUXXHSTVMM01.hosting.ss\MSSCVMMLibrary" -OverwriteExistingFiles

10.Restart BITS Service. open powershell as an administrator and run:

Restart-Service BITS

11.Check if the service is running properly by executing:

Get-Service BITS

12.Open the SCVMM console and go to the Jobs section.
13.Look for any failed jobs related to library operations.
14.Click on each failed job to view detailed error messages for more information.
