Hi! We have a customer that is using Parallels. They need to connect to a network share located in their LAN. Accessing the network share works fine but the shared folders on the server do not appear. When accessing it from MacOS the shared folders appear. So it is not a permission issue. I've also tried it on a Windows client in their network. I guess it's probably just some configuration in Parallels but I've never used Parallels myself.
