I have never tried win 10 as a server by itself.
I always install wamp or xampp on win10 since that is more compatible with the online linux servers.
I assume you have enabled IIS to start with.

But anyway have you tried the UBB test script first?
It may lead you to where the issues are.

BTW there are very very few users here that use windows as a server.
In fact BellaOnline is the only one I know of today.
