By default, access to network shares is not allowed. You either need to remove the BlockNetworkFiles=y¹ setting from your configuration or specifically allow that network share if you want to access it without removing the setting.

Use one of the following:

Direct access²³ (read+write) [no sandboxing]:

OpenFilePath=*\myshare\*

OpenFilePath=*\localhost\myshare\*

OpenFilePath=\Device\Mup\localhost\myshare\*

Great, thanks. Is there anyway to grant read only access to network shares?
