I have a 2008 R2 terminal server and a new 2016 server. under mstsc.msc (RDP) I am trying to connect to the 2016 server from the 2008 R2 and I am getting the RDP can't connect to remote computer for one of these reasons error. Everything is configured correctly and I can RDP from 2016 to 2008 R2 without an issue. 2008 R2 is using RDP 8.1 client and I have removed the NLA and firewall and tried still the same issue. I also tried another 2008 R2 server that is not RDS and same issue.
Ran netstat -ato and port 3389 is not listening on server 2016
Went to the regkey path and verified the default port is 3389, did not change it.
I did verify the TLS patch was installed but I do not know what else I can try to fix this issue, RDP works except from 2008 R2 to 2016 server OS, anyone got any other things I can try?
The security is set to negotiate and no NLA
I also was able to RDP from 2008 R2 to 2016 server without issue
I have found that other people have encounter this issue with server 2016 but not definite fix has been listed.
