I have 2 PCs running windows 10 in my house. Lets call them PC1 & PC2. They are both connected over the network (hardwired) and sharing is fully enabled between them with zero issues. PC 2 is my plex server as well. Today I turned PC 1 on, and PC 2 is no longer listed in the network. The Plex media server still shows up. And from PC 2, PC 1 shows up and I am able to transfer files to and from. What happened and how can I fix this? I have restarted both and the exact same situation appears! No changes were made from last night when I was able to see both PCs from the other. Thank you for any help!
