today i was trying to print a document, a very important file I was working on in my windows 10 guest machine. I was using virtualbox, the best way to print easy my file was to just create a shared folder between both the guest and host machines since both machines are using windows 10. I tried to access my network and it was empty.

Open Folder

\\VBXOSVR is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

The specific netowrk provider name is invalid


These are the troubleshotting stpes i took to make it works:

1. Make sure you have Guest additions installed on your guest machine. [reboot required after installation]

2. Be sure that you have added the host folder in the shared folder settings

3. Be sure you have set your network connection as private and network discovery. you find find the settings here:
Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings


i hope that helps. I was able to fix this error by checking the three troubleshooting items above.
