Can confirm on Windows 10 Pro for Workstations 2004 that Windows does in fact allow hostnames > 15 characters.

 

difficult to determine which is which

 

LiamG14I do believe that when I set my long hostname on my new installation above a warning popped up showing the truncated NETBIOS name.

 

UPDATE: I discovered a rather unpleasant limitation to the above. I named my machine DellOptiPlex390MT-1, which worked. However, thanks to the NETBIOS limitation, Windows shortened that to DellOptiPlex390 for network shares. Doesn't sound like a good idea for the share name and hostname to not match, + there's already a machine on my network with the *390 as its hostname. So I guess I'll rename it to DellOptiPlexMT1 instead since it's the only Dell OptiPlex MT I have that runs Windows.

    That's exactly what I was referring to in the UPDATE section of my previous comment.
