Windows 10: Browsers crash and freeze up - but only when joined to domain.

We have just upgraded from 8.1 to 10 Enterprise at the school were I work. In many classrooms we started receiving reports of browsers crashing and freezing up momentarily. This happens most often with Chrome but I have seen it with Firefox and Edge. We tried uninstall/reinstall on all browsers, leaving and rejoining the domain, /flushdns, /releaseip, clearing browser cache, repeated reboots, checking for latest NIC drivers, Windows updates, etc. all to no avail. Then I tested the same machines with a USB wifi adapter and unplugged the ethernet cable. No problems with any browsers. Then I left our domain but reconnected the network cable just to have internet access. Again, smooth sailing. So, I rejoined the domain and the problems came right back. I don't believe we changed anything on our group policy administration or dns/domain controller before we upgraded the classroom computers. I'm not certain but think we might be using roaming profiles as well (I don't administer this stuff but am trying to help our with my limited network skills). Are there certain domain, group policy, or dns settings that we should check since the classroom machines now have a different OS? Any help would be appreciated.

Settings app crashing when I click "About" tab

I'm trying to join my PC to a domain, and every time I click the "About" tab the Settings app just crashes (window vanishes, back to Desktop). How can I join the domain, or prevent this crash?

 

Remote Desktop Connection is not asking for login credentials

The only solution I've found is to manually add a set of generic credentials for the target RDP host in the credentials manager on the client. Note that I only see this behavior when my client machine is not joined to an AD domain (specifically logging
on to the client using a MS account). The target RDP server is joined into an AD domain.

The same server can be accessed normally from a Windows 10 host joined to an AD domain (not necessarily the same domain as the target).

Hope this helps.
