Remote Desktop Protocols and Virtual Network Computing
RDP Java and VNC are supported on Windows, Linux, and Mac operating systems, while RDP ActiveX is supported
only on Windows. Most Microsoft workstations and servers have RDP server capabilities that can be enabled for
remote access, and there are a number of freely available VNC servers that can be downloaded and installed on
most operating systems. RDP and VNC also supports HTML5 and Smart Access selection. The RDP and VNC clients
are automatically delivered to authorized remote users through their Web browser in the following formats:
•
RDP Java – RDP Java is a Microsoft Remote Desktop Protocol that has the advantage of broad platform
compatibility because it is provided in a Java client. The RDP Java client runs on Windows, Linux, and
Mac computers, and supports full-screen mode. On Windows clients, SMA/SRA appliances support many
advanced options. On Mac OS X 10.5 or higher, RDP Java supports the Mac native RDC client.
•
RDP ActiveX - RDP ActiveX is also a Microsoft Remote Desktop Protocol. The RDP ActiveX client only runs
on Windows, and is not supported on Mac or Linux computers. Four advanced options are supported by
SMA/SRA appliances for RDP ActiveX.
•
VNC (Java) - VNC was originally developed by AT&T, but is today widely available as open source
software. Any one of the many variants of VNC servers available can be installed on most any
workstation or server for remote access. The VNC client to connect to those servers is delivered to
remote users through the Web browser as a Java client.
RDP 7 Support
The SMA/SRA appliance supports connections with RDP 7 clients and supports the RDP 7 feature set. RDP 7 is
available on following operating systems:
•
Windows 10
•
Windows 7
•
Windows Vista SP2
•
Windows Vista SP1
RDP 6 Support
The SMA/SRA appliance supports connections with RDP 6.1 and RDP 6 clients, and supports the RDP 5 feature set
plus four RDP 6 features.
RDC 6.1 is included with the following operating systems:
•
Windows 7
•
Windows Server 2008
•
Windows Vista Service Pack 1 (SP1)
RDC 6.1 incorporates the following functionality in Windows Server 2008:

NOTE:
RDP 6 and RDP 7 end client systems must have the client installed on their system. The SMA/SRA
appliance does not provision the mstsc client and utilizes the locally installed client for those
connections.
Application Protocols Using RDP
Applications protocols are RDP sessions that provide access to a specific application rather than to an entire
desktop. This allows defined access to an individual application, such as CRM or accounting software. When the
application is closed, the session closes. The following RDP formats can be used as applications protocols:
