RDP Unavailable on Server 2012 R2

18 Sep

I recently had a VM show RDP errors on PRTG. All of the RDP settings and firewall rules are controlled via GP, and all other server were working as expected.

However, I still failed to connect via RDP. I could still get in via the Hyper-V console and ultimately the only fix was disabling and then re-enabling IPv6 on the Network Adapter.
