KB40513 - Configure HTML5 Access for Standard Encryption (Non-Single Sign On)

This article provides step by step instructions how to configure HTML5 Access for Standard Encryption where an RDP session will connect with the standard Windows logon screen.

When connecting with HTML5 Access, end users are expecting the standard Windows logon screen.  If HTML5 Access is configured for "Network Level Authentication" or "Allow the server to choose" (default option) and the RDP endpoint is configured for Standard Encryption, the following error message will occur:
 

Connection Error

The remote desktop server encountered an error and has 
closed the connection. Please try again or contact your 
system administrator.

If the end user would like to connect using HTML5 Access and see the standard Windows logon screen, then Standard Encryption must be configured on the PCS device.  Also, RDP endpoint should be configured for Standard encryption (non-NLA).  For more information, please refer to Microsoft documentation depending on the version.
