We have a 2012 R2 Terminal Server that has a UCC cert that was created on an Exchange Server on the domain. The SAN name is remote.xxx.xxx. When I attempt to log into the Terminal Server using RDP on an 8.1 client, I get the warning "Name mismatch". The requested remote computer reports the internal server name, not the outside FQDN. I'm including a pic with the error. If I figure this out before a reply, I'll include a fix for anyone else running into this.
