When it comes to my kids, I'm a Nazi. They don't play games online. Maybe I'm a bad dad... but at 9, 11, and 11, I just don't feel they need to go online and mingle with creepers. Real ones.... not the minecraft variety.
So they could play together easily, I built a Minecraft server on a Linux VM for them. It's in creative mode, as my wife also uses it, and they all have their little worlds on there. That works great. It's the self-hosted LAN games they're having issues with.
The problem is when they want to spawn their own games and play in survival mode without the server. My two boys can see each others' games, but my daughter cannot see their games, nor can they see hers. I've even tried disabling Windows Firewall completely, but that doesn't seem to work either. All PCs can ping each other, see our main Minecraft server on the network, etc...
This is only an issue with my daughter's PC... and it's only an issue with the advertisement part of the LAN game. If I enter IP-port into "Direct Connect", she can connect just fine. I can completely disable all firewalls between the kids' PCs, but her game will still not see either of the boys' games show up in her multiplier game window (nor will they see hers). The boys will see a hosted game between their PCs just fine, though.
A little about the environment:
- PCs are on a Windows 2012 domain
- Firewall rules are pushed via GPO
- Java SE is blocked via "Kids" GPO to talk to internet; can communicate on local /24
- They're on the same IP subnet, same wireless network, inside the same house, etc...
- All Kids PCs running Windows 8.1 current on updates (patched through WSUS)
- All Kids PCs talk through a proxy server running Prixoxy, which can communicate with all minecraft servers
- All Kids PCs running latest version of Java and Minecraft
- I did build her PC about 6 months before I built theirs. I don't typically do things differently, but there's always that possibility...
