RDS - the connection has been terminated because an unexpected server authentication certificate was received from the remote computer

Hi,

we have an intermittent issue whenever some users connect to our RDS environment. our RDS is setup is we have 2 RDS servers (2012R2) with round robin DNS configured. Users will need to connect via rdp to hostname.domain.com (DNS) but for some users, they wil get the error "The connection has been terminated because an unexpected server authentication certificate was received fro the remote computer".

Now, i didn't get this error before until i installed the win 10 build 1607. 

i found this technet forum were a workaround is able to fix this. You need to replace the current mstsc.exe and mstscax.dll from a system still running win 10 build 151.

is there a permanent fix already for this issue? thank you very much.
