I'm trying to automatically update a shared folder on a HyperV machine when a folder from the local maching gets update. I've tried using Task Scheduler with Robocopy command and Powershell commands without luck. It seems like there's a security issue between the two computers but I cant seem to find where this problem exists. I've tried turning on printer and file sharing, allowing access to "everyone" on both folders, veriifying VM settings to allow file sharing. Any other input would be helpful, thanks!

What account did you configure the task to run as? If it's a local account, then both systems must have a local account with the same name and password. If it's a domain account, then RDP to the source machine with that account and verify that it can access the destination share. Have you reviewed both the share permissions and the folder permissions on the destination machine? The task scheduler does not perform a full logon, it does a user impersonation. The main implication is that drive letters are not mapped. Use UNC path notation, \\servername\sharename\foldername. Add a transcript to your script and capture the error that is occurring. https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.host/start-transcript?view=powershell-5.1

The local account description that you provided might be the problem. The two computers (host machinge and HyperV) have different local accounts with different credentials. To be clear, I have to have the same username and password on both the local and HyperV machine to allow the files to transfer with the Powershell script or Task Scheduler?

The reason I ask is because I can copy and paste between shared folders between host and HyperV but cannot get the Powershell or Task Scheduler to move the file automatically between host and HyperV. I can successfully get the Powershell script and Task Scheduler to transfer within the HyperV environment but only run into issues when trying automatically move between host and HyperV.

If you are using local accounts then they need to be the same name and password. The alternative is to use an Active Directory account but you have not said if this is an AD environment or not.

You haven't said how you share the folders that you are using. Are they all Windows network shared folders or is Hyper-V providing the sharing?

I have VMWare workstation installed on my laptop. For my test VM, I configure my main test folder to be shared with the VM. It's not a network share where I have to map a drive, but it does show up under Network. When I log on to the VM, it's already there. The VMWare tools provide the interface to the host, not the normal Windows networking functionality,

Are you doing something similar with Hyper-V? That "shared folder" might only be visible to the user who is logged on to the desktop.

The local account username and password matching was the fix. Thanks for the feedback and help!
