When initially navigating to it in the virtual machine, VirtualBox links it to the VM as a Network name like so: Maybe this might help give us a clue as to what the problem MIGHT be: If there is a "Virtual IP Address" I could use/try, what might that be? Something that I might be able to tell SyncBack to use OTHER than a "UNC Path"? Rather than an "IP" address, does anyone have another suggestion that might give me a clue as to how VirtuaBox "Networks" shared folders to the Guest OS's? I don't think that will work as I think this is a "Virtual" network connection. If I understand the suggestion, on the SyncBack Forum, they have suggested that I use an "IP" address instead of a "UNC path". which suggests that the resource name entered is invalid.Ĭan you please try using ' IP Address' instead of the host name in the UNC path to see if it resolves your issue(for example: \\IP Address\ DON.T_DELETE_-_Drawings\)įYI, I have changed the name of the folder to something simple (only lower case letters, no spaces, no punctuation) and I still get the same error message. You can refer to this link for the return value: Is returned from Windows, when SyncBackPro is trying to establish a network connection using Windows API call.
