I have a collection of two RDS virtual servers
RDS02 under Windows Server 2008 R2 and one RDS/REMOTEAPP virtual server
APP01 under Windows Server 2012 R2.
RDS02has the same configuration
RDS02can establish a connection to
APP01via 443 or 3389 port
telnet APP01.domain.local 443OK
telnet APP01.domain.local 3389OK
RDS01can connect to
RDS02cannot connect to
I suspect a security layer negotiation issue but I have no idea how to solve this problem.
- In Internet Explorer, TLS 1.0 / 1.1 / 1.2 protocols are enabled in Internet Settings.
- In MSTSC application, prompt for credentials opens and after validate, a connection progress bar run infinitely and display: Securing remote connection
Any help will be welcome
