Windows 10 build 1511 PCs don't/intermittently appear in their own or other Windows 10 build 1511 network folder

The November Windows 10 build 1511 is causing PCs either to not appear at all or intermittently appear in their own or other Windows 10 build 1511 network folders, but they do appear in Windows 10 PCs network folders that are running the previous build. This appears to be a Microsoft screw up.

Anyone know how to fix this or if Microsoft is working to correct it?
