We recently had a client that needed to wipe out their Nutanix storage and virtual machine cluster and to do that we needed to load a Nutanix ISO from a Windows server. No matter what source we selected we received this error message:

The source files could not be found.

windows smb10 cifs the source files could not be found

So what we Did is install a brand new Windows Server 2022 Azure Edition in Microsoft Azure period now we know that SMB 1.0 has been correctly vilified by Microsoft because of its lack of security. It’s a dangerous protocol to use in today’s world.

However SMB 1.0 / CIFS still shows as an option even in Windows Server 2022 Azure Edition so we didn’t think we should have any problems. Well it turns out we were wrong; you cannot install SMB1.0 onto Windows Server 2022 Azure Edition but you can install SMB 1.0 / CIFS onto a:

  1. Windows Server 2019 machine in Azure
  2. Windows Server 2022 box in an on-prem Hyper-V
  3. Windows 10 LTSB 2016

If you want to install SMB1.0/CIFS onto your Windows Server 2019 in azure what you have to do is install an old version of Windows Server windows Server 2019, add SMB 1.0 / CIFS:

1. Install a fresh copy of Windows Server 2019 to a temporary server  and join it to my domain. Make sure the build number is 17763.737 or lower.

2. Attach the Windows Server 2019 evaluation ISO to the server. Install the SMB1 feature and enter WIM:E:\sources\install.wim:4 as the source.

3. Reboot the server once the feature is installed

4. Install all the latest updates to the server and reboot

5. Share the C:\windows\winsxs folder on the server. Give “everyone” read permission.

6. Go to the server where you are unable to install SMB1. Do the installation but put the source as \\servername\winsxs that you shared in step 5. The installation will complete


The other thing you can do is simply install Windows Server 2022 on your on premise Hyper V and it just works.

In our case we couldn’t get an old copy of Windows Server 2019 and we had to do the install in Azure so we ended up installing Windows 10 LTSB 2016 in azure And that comes with S MB 1.0 enabled by default. at that point our Nutanix machine with was able to copy files from our Windows 10 Long Term Servicing Branch (LTSB).
