So without being too hyperbolic, I'm about to die! I've spent too many hours with 0 progress and am beginning to resent pcs in general. I have 3 pcs (2 desktops and a laptop) all wired via gigabit. In short - my desktop (a) can see itself and my laptop under network, but not the other desktop (b). My laptop can see itself and my desktop (a) but not the other desktop (b) My other desktop (b) can't see itself, but can see my desktop (a) and my laptop. All I've come up with so far is the miserable reformatting of my desktop that presumably is the key to the issue (b). A few things happened after such that may point you networking geniuses in the right direction. A) it showed up on the network immediately after a fresh Windows install. B) it disappeared after I changed the name. C) I got it to show up spontaneously after a full shutdown (not restart) but may have been coincidence. What happened next was this - upon restarting either the laptop or desktop (a) it continued to see itself and the others continued to see it. After restarting desktop (b) itself - it once again no longer saw itself nor did the others see it. Further shutdowns/restarts were fruitless. Also rebooted both router and switch. I'm at a loss, yet ocd enough to not move forward with anything until I fix this. Oh I forgot to add, they can see plex media server if it is running on the desktop (b) and if I type in the address they can reach the Desktop (b) and browse it just fine. Simply nothing shows in explorer Learn me sum networking101!
