I set up a new storage account in the Azure portal, created a file share and then hit the "connect" button in the interface.
net use l: \\sharename.file.core.windows.net\uploaded-images /username accessKey
I put in my key but had no luck:
System error 53 has occurred.
The network path was not found.
I checked my firewall and that wasn't the issue (on the outbound side).
Thanks, John
