TLS 1.2 client hello triggers TCP Reset from 2012 R2

Struggling with a PKI implementation in my lab (ADCS 2012 R2) and cannot for the life of me figure out where I have gone wrong.

Got all the way to the point of being able to generate SSL/TLS certs for an IIS server and make the binding. Also used the NARTAC tool to shut down SSLv2/3 + enable TLS 1.0-1.2. Using testssl.sh I can verify that SSL is disabled and can get a handshake for TLS 1.0 and 1.1, but every time the client hello for TLS 1.2 is received the server sends a TCP Reset. The system logs show the pair of SCHANNEL 36874 and 36888 error IDs that correspond with the resets. Error 36874 suggests that the client hello is presenting cipher suites that aren't supported by the server.

This is where I hit the brick wall, and my searching the interwebs is not yielding a winner. I can all but guarantee I've overlooked something glaringly obvious. However, the blinders of frustration are preventing me from seeing it.

Thoughts?

EDIT 1

Found that I can successfully get a non-domain joined 2012 R2 IIS server to respond to a TLS 1.2 hello packet. So my issue appears to be related to being a domain joined system. Still haven't solved that part of the equation.
