I wanted to reply again with another piece of information, in case someone else is running into this issue.

Playing a LAN game over Hamachi DOES work in Win10, so that's a possible solution some people can use until (if?) this issue is worked out. 

I'm having the same issue as CalmPhil was earlier after updating to the Win10 Fall Creators update. The game loads for everyone else in multiplayer but me and eventually the connection times out.

I was able to roll it back but my friend (who is also having the same issue) wasn't able to roll back due to recently upgrading from Windows 8.1, so he didn't have an older version of Win10 installed to roll back to. 

I just want you guys to be aware of this, something changed in the way Windows 10 handles networking or something that completely breaks MO or CnCNet in general. My friend is going to create a Windows 7 partition and play MO that way, but it's kind of annoying to have to install a second OS just to play our favorite game because Microsoft broke something. Due to the way Microsoft tends to force updates upon people, you're probably going to see this issue more and more going forward.
