MAC版RDP访问Windows远程桌面报错问题的解决(The certificate or associated chain is not valid - RDP error)

The certificate or associated chain is not valid - RDP error


Hi,
I am getting the following error "The certificate or associated chain is not valid" when I RDP from my MacBook Pro OS X Yosemite version 10.10.4 to my workstation.
I am using Microsoft Remote Desktop Connection Client for Mac version 2.1.1.
 
Please advise.
MacBook Pro with Retina display, OS X Yosemite (10.10.4)

Answer:
In RDC, go to Preferences and then Security tab.  Then check box that says "Always connect ...".
